How do you put the parts together? What parts do you need to build your own computer? In pure computer nerd speak, somebody could say, You need to have KVM, CPU, MOBO, HD, RAM, CD/DVD, A/V, and a good NIC. If that sounds like the kind of technological jargon that makes you worry, want to pull your hair out, or scream at the kid at the computer store. Then you have found the right technology guide. This is still an early draft of this guide and it going to need a couple of revisions before it is useful to the general public. If you see something that needs to be changed just let me know and I will make sure it gets updated! Why write this guide? David Borys asked a question about computer hardware and the internet did not have a comprehensive clear and concise answer. I have solicited both David and Andy Phelan to make sure than the content is clear and concise enough for the new computer user to be able to understand.
- Warning: Make sure that you know what you are getting into before you
decide to build your own computer! A note to the keyboard cowboy, this guide
is operating system free and discusses x86 architecture, and the current state
of technology. This is simply the relatively well-informed opinion of an
educated computer user. I post this guide to the internet for the express
purpose of providing information and allowing discussion. I do not warranty,
certify, or provide any acknowledge any responsibility for technical
assistance, or catastrophic system failure.
You do not need to worry if you are not up to date on all
of the acronyms and jargon that surrounds discussions of computer technology. I
am going to go thorough each part in detail then at the very end of this
technology guide I will describe two hardware configurations, and how to put
them together. The objective of
writing this guide is that after reading this guide on, What do you need to
build your own computer? You will have the knowledge base to think about what
technology you can use to build a computer and what new technology is
developing. If you see a dotted underline allow the mouse driven cursor to hover
on the acronym and a box will appear that tells you
what it means. I also have an
Acronym List at the end of this guide.
-
With a little due diligence and some reading you can build your own
computer. Every personal computer built and sold in the United States is
modular. What does that mean? Anybody can build a computer without having to
rewire, build, or really do any electrical engineering. Almost every computer
part simply has to be correctly installed and then for some devices you just
have to setup the software. When you make the decision about what type of computer you want to build two
basic scenarios exists that I am going to provide sample computer parts
configurations for both 32bit and 64bit x86 architecture system.
From this point in the document
you have officially started reading the guide, “” You can certainly are
welcome to read the guide
from start to finish, but if that is not your intention, please finish reading this paragraph before you
jump ahead to different sections of the guide. The
first part of this guide is the navigation list all
the computer parts, that you need to understand to build a
computer. The internal
computer parts include the
computer
case,
power supply,
CPU,
CPU Fan,
motherboard,
hard
drive,
RAM,
floppy
drive,
disc
drive,
audio
card,
video card, and the increasingly important
network
interface card. External computer parts
include the
keyboard,
mouse,
monitor,
and the
UPS.
The second distinct part of this guide is the practical application of your
newfound computer hardware knowledge, explaining what parts you need
to build your computer. I am going to discuss both a
Sample 64bit
Parts Configuration and a
Sample 32bit
Parts Configuration
explaining the fundamental differences and challenges associated with both
hardware configurations.
I will then discuss how to assemble that sample computer parts configuration
in the final section of this guide in the form of the rather monolithic, “Building
The Computer” section,
recently I decided to include an appendix on Troubleshooting Your System Configuration, you can thank me later.
If you find this guide useful, then please consider linking to this entry.
A keyboard is a fairly simple device
that allows you to enter text one letter at a time. Keyboard represents the K in KVM, while most computer nerds (myself included) spend large amounts
of money on an ergonomic natural split keyboards and wireless keyboards. If you are really going to
spend hours in front of the computer please make sure you have a comfortable
keyboard with a nice gel wrist pad to help prevent health problems.
- New Technology You can officially get at least two
kinds of wireless keyboards that plug into the computer s motherboard
through a USB or PS2 connection. Wireless keyboards are great you can move
around the room and type, remember keep some spare batteries around!
- Industry Standard Without question if you have ever
used on the USB ergonomic natural keyboards are faster and are growing in
popularity. What is a natural keyboard? When you look at a bunch of
keyboards at the store, they are the ones with the giant split down the
middle of the letter keys so that you have to type with two hands.
- Technology History PS2 connection keyboards
are everywhere if your keyboard has a wire and plugs into the motherboard
with a small circular interface this is probably what you have. This classic
technology standard will probably be around forever, until the wireless
keyboards become an affordable Industry Standard.

The mouse puts the M
in the technology acronym KVM (sometimes people call this the rodent or other
nicknames usually associated with mice. While technically the mouse is
optional, you will find that practically speaking the mouse is a necessity in
modern computing.
- New Technology Wireless keyboard and mouse combos
are becoming relatively cheap and are probably the wave of the future.
Wireless mouse and keyboard technology can be a little slower, require
batteries, and software or hardware configuration. Internet gamers contend
that the weaker the batteries get the slower your mouse and keyboard get,
but this type of computer user is very demanding and spends hours playing
online games.
- Industry Standard The relatively recent industry
standard is the optical USB mouse with a third button and a selection wheel.
- Technology History Almost every mouse in
existence uses the classic industry standard PS2 connection, having an
optical mouse is cool, but does not provide a large enough difference for
everybody to run out and buy one overnight.

Make sure you
have the right size case and all the necessary case fans, modification kits,
and of course, cable ties to secure the wires.
- New Technology Right now, a new design revolution is
occurring with liquid cooled cases, small cube traveling cases, and massive
modifications including colored lights, glowing fans, neon switches. This is
a cool trend because so much equipment is hitting the market that prices are
quickly falling!
- Industry Standard Most cases are your standard ATX
full to mid tower setup that comes in the standard colors of black or white.
A full tower comes with four external 5.25-inch device bays in the front of
the case, while a mid tower usually has two of these device bays.
- Technology History Think back to the days of
computer cases that say underneath a monitor not under a desk. I am glad
these cases have gone the way of the dinosaur they are difficult to work
with not module and constrain your ability to upgrade your computer
yourself. If you are going to spend hundreds of dollars to build a computer
you want to be able to upgrade the parts without having to purchase another
computer.
Back to Top
Sometimes this
device comes with the Computer Case, but you need to make sure you have enough
power to run your CPU some people use slang and call this the chip.
- New Technology Power supplies are getting much more
powerful these days exceeding 500 watts of power. They now have serial power
cables to connect to SATA devices. The faster your CPU the more power you
are going to need, make sure and check the manufactures documentation for a
power recommendation.
- Industry Standard Right now, the average power
supply does not have serial power cables and is between 300 and 500 watts of
power.
- Technology History Power supplies exist below
300 watts of power, but they are somewhat older and cannot support the
demands of new technology. For this device to functionally change an entire
new line of products would be required. For the most part only the power is
going to change not the actually power supply.
Back to Top
(CPU)
Some people use slang and call this the chip, but it is one of the most
important parts of the computer.
- New Technology Both Intel and AMD are now offering
64bit technology for personal home computing. I am a huge fan of the AMD
64bit chipset, because it uses a duel core technology that simply blows
Intel out of the water. (Disclosure: I own a 64bit AMD chip.)
- Industry Standard Right now most people have Intel
or AMD 32bit processors running over a gigahertz.
- Technology History According to Moore’s Law every
year the computing power of a chip will double. Any 32bit processor
running under a gigahertz is now considered slow. The frantic race for speed
has produced a large number of chips in the market that companies are not
designing technology for anymore. This means that you have to be careful
what kind of chip you buy, because if your motherboard fails it might be
difficult to find another one, and if your chip fails you are going to have
a hard time finding a replacement, except on eBay.
Back to Top
, because you
will need a special fan to cool this device, seriously this is incredibly
important.
- New Technology You can get liquid cooled fans
and specialized exhaust systems to make sure your processor does not
overheat.
- Industry Standard Make sure you have a fan that is
designed for your processor.
- Technology History This technology has
not changed that much, but the older fans do not work on modern processors,
make sure you spend the money to buy a new fan.
Back to Top
This is one of
the most complex parts of the computer and if you do not buy a quality
motherboard, you will regret it for years. A motherboard can possibly have
audio, video, networking, and other specialized cable connections already
installed. Some people really like this kind of motherboard it can potentially
reduce your purchase to eleven items instead of as many as twenty.
- New Technology 64bit motherboards with all the
really cool technology included: SATA, Fire Wire, USB 2.0, next generation
video, and fancy audio.
- Industry Standard Most motherboards do not have any
onboard video and audio, providing limited support for new devices without
purchasing additional interface cards.
- Technology History Motherboards are usually
associated with the processors they support. Any motherboard that uses PC133
memory or slower is probably considered somewhat older technology, and is
starting to become obsolete.
Back to Top
Right now I am a
major fan of the
SATA drive, but that does not mean that a quality
ATA drive
will not work for you, this device stores all of the information on the
computer and needs to have a large capacity.
- New Technology SATA! The new hard drives use a
different power and motherboard connection cable that makes them much
faster. Running the required ATA150 controller card for serial hard drives
is what allows a major increase in the speed of data transmission.
- Industry Standard Most hard drives are IDE devices
that connect to the motherboard through an ATA133 controller card built into
the motherboard or attached through an expansion card attached to the
motherboard. The current industry standard is a 7,200 RPM hard drive with at
least 8 MB of buffer.
- Technology History Any computer using
ATA100 technology or slower with a hard drive speed of 5,000 RPM is now
considered to be somewhat older technology.
Back to Top
Sometimes people just call
this Physical Memory.
- New Technology Any Memory speed above PC2000+
is new technology.
- Industry Standard This PC133 Memory was produced in
mass quantities and is everywhere .
- Technology History Any Memory that is slower
than PC133 is somewhat older technology.

I really do
not like this devices, and have no interest in discussing them, but some people still love them.
They are still the 1.44
MB single disc drive
you remember from years ago, this
truly a legacy device.
Back to Top
Compact disc
(
CD) or digital video disc (
DVD) drive (Maybe even a
CD/
DVD burner if you
want)
- New Technology With two competing media types DVD+R
and DVD-R this technology was fragmented and has now gone from DVD5 to DVD9
nearly doubling the data capacity of a DVDR.
- Industry Standard Almost any computer is going to
have a DVD or CDR drive.
- Technology History A computer that
does not have the capacity to record with either a DVDR/CDR probably has a CD
drive, which is the minimum requirement for a modern computer.
Back to Top
If you want to
be able to hear sound, then you better get one of these cards or buy it built
into the motherboard.
- New Technology You can get new audio cards
that have Dolby Digital 5.1 and other amazing sound configurations.
- Industry Standard Make sure you get at least a 24bit
audio card.
- Technology History The lower end of sound
cards only matters if you care about what kind of sound you are have. My
64bit computer does not have an audio card, because I have not bothered to
install one. It only matters if you want to hear sounds!
Back to Top
For some people
graphics is the most important part of a computer, you can get this card built
into the motherboard or purchase it as a separate card.
- New Technology The
All-In-Wonder 9800 Pro 128MB 8x AGP Video Card, is certainly near the best
technology at just under $300.
- Industry Standard Most video cards are 64MB and
produce quality graphics.
- Technology History Any video card with less
than 64MB of memory built into the card is definitely somewhat older
technology.
Back to Top
Want to connect to the internet, then you better make sure you have one of
these cards or purchase it built into the motherboard.
- New Technology Wireless network cards including the
new amazing 802.11 standards A/B/G/G+ are allowing people to connect to the
internet without wires.
- Industry Standard RJ45 or Category 5e/6e fast
internet connections using Network Interface Cards are the most common form
of Network Interface.
- Technology History Modems all of them are old
they use RJ11 cable standards, the same as the telephone system.
Back to Top
One need one of these!
- New Technology Digital flat screen LCD.
- Industry Standard CRT Flat panel
- Technology History Recently the market has changed
from being all glass CRT monitors to flat panel glass monitors. Then the
entire market changed with the advent of plasma screen technology and liquid
crystal displays.
Back to Top
A Uninterruptible Power Supply is the modern version of a surge
protector.
- New Technology Voltage regulations, surge
protection, and a long batter backup.
- Industry Standard A surge protector with short
batter backup.
- Technology History It used to be that only companies
and true computer nerds had battery backup systems. While a surge protector
is essential for any computer owner, having at least a surge protector with
a batter backup should be a requirement.

I have put
together a minimum list of parts that you will need to build a 64bit computer
that conforms to my standards. Most of the parts I have included in this sample
64bit parts configuration also work with 32bit configurations. The main
difference is going to come from the motherboard and CPU. I will go ahead and
talk about each part you need and list some of my part choices. This section is
does contain some of my personal bias in the form of my opinions, but that is
why you read this kind of guide right? To find out what I think about a sample
parts configuration. I am going to discuss parts in terms of High End
Technology, some people call this the bleeding edge of technology, that might
have something to do with the higher prices or with the fact that you experience
more problems with less established products, and I am will tell you what I
consider to the industry standard. The parts and prices I suggest are simply for
example purposes, I do not own stock in any of these companies, but I will let
you know what parts I have had serious problems with in the past.
- CPU – It is no secret that I am
a big fan of the AMD 64bit chips. They duel-core architecture that is native
in 64-bit chips will allow you to upgrade your CPU in the future by adding
an additional L2 cache processor, Intel does not have that option. My friend
Seth works for Intel so I will not say anything exceptionally terrible about
the company, but my allegiances are currently on the side of AMD.
- High End Technology AMD
ATHLON 64FX 5100 OEM ($749)
- Industry Standard – AMD ATHLON 64 2800+
RET ($176)
- CPU Fan – This fan is
important, because it keeps that really expensive processor cool. Make sure
you get a nice one whatever you do, having a CPU Fan burn out and toast your
chip is a terrible experience. I speak from personal experience, buy a
quality fan!
- Industry Standard – FOX K8 OPTERON AMD-64 FAN ($40)
- Case – My personal case is a
Codegen
(S-201 ATX Server Case with 17Bays $170 before the cost of the power
supply), which is way bigger than most personal computer users need. I have
had several different cases and have been happy with most of them.
- High End Technology – EVERCASE ECS5000LX-B BLK SERV ($149)
- Industry Standard – XION BLACK GAMING CASE 450W ($89)
- Motherboard = Right now I am on a GIGABYTE kick and have been suggesting
these motherboards. Remember that you have to make sure to purchase a
motherboard based on what CPU you want to have! Motherboards only support
certain CPU’s I also recommend new computer users purchase a
motherboard with built in audio, video, and network interface.
- High End Technology – GIGABYTE 8KNXP 875P FSB800 8X L/R ($229)
- Industry Standard – GIGABYTE 7N400PRO2 GBLAN SATA 1 ($125)
- RAM – Pick your ram
based on what your motherboard and CPU support! I know it gets expensive,
but you want to make sure you have at least 512MB of RAM.
- High End Technology – 512MB PC3500 433MHZ DDR ($139)
- Industry Standard – 512MB PC2700 333MHZ ($99)
- Floppy - MITSUMI 1.44MB FLOPPY DRIVE ($12)
- DVDR – When you build a
new computer you have to make a choice about moving to the dual layer DVD9
format or staying with the DVD5 single layer format. Personally I still have
the DVD5 format which has a 4.7 gigabyte capacity.
- High End Technology – OPTORITE 12X DVD+/- DUAL LAYER BL ($99)
- Industry Standard – SONY DVD+/- 4X WRITE ($60)
- SATA – I am
really a huge fan of the SATA Hard Drive. You can get other types of hard
drives, but really on a 64bit computer you might as well realize the best
potential computing speed by getting a faster hard drive.
- High End Technology – WESTERN DIGITAL 250GB 8M SATA ($199)
- Industry Standard – SEAGATE 120GB 8M SATA ($105)
- Keyboard – I really do enjoy my natural keyboard with custom gel wrist
guard.
- High End Technology – MICROSOFT Natural Elite Keyboard ($35)
- Industry Standard – Check the local computer store you can get a
keyboard for ($3-$10).
- Mouse – Buy what you like to use, if you do not know what you like go to
the store and look at them.
- High End Technology – LOGITECH MX500 OPTICAL MOUSE ($49)
- Industry Standard – Check the local computer store you can get a mouse for ($3-$10).
- Monitor – This is probably the most important part of a computer for
most people, because this is what you you spend your time in front of on a
daily basis. Make sure you think about how big of a monitor you will want
and what you want to do with your computer.
- High End Technology – VIEWSONIC X910 19″ LCD Display ($650)
- Industry Standard – VIEWSONIC 19″ E90F FLAT ($200)
- UPS – Please buy
one of these!
- High End Technology – APC Back-UPS XS 1500VA 865 Watts ($200)
- Industry Standard – Belkin Enterprise Series 900VA UPS 540 Watts
($120)
Back to Top
Prices seem to range between $600-$1500. This is still a work in progress!
- CPU = AMD SEMPRON 2400+ RET ($72)
- CPU Fan = ($20)

This is still a work in progress!
- Once you have all of the parts together in one place. Find a flat
surface that is clear, static free, (Not on the carpet, near a plastic
table, or plastic tablecloth) and has enough room to work. Make sure you
have a static free Philips Screwdriver that is not magnetic. Get our an
empty coffee cup to put the screwdriver in when you are not using it and to
store the screws that come with the next hardware. I know this sounds simple
and easy to do, but if really does make a difference to be prepared. Make a
stack of all the documentation that came with your devices and then make
sure you take the time to sit down and read everything! This guide does not
cover every possible step that you might need, and reading the manuals is a
good habit to develop.
- Take the motherboard out of the box and make sure that it is still in
the static free foil bag. Place the computer case on the work space. Once
you have the computer case open and have put screwed in motherboard risers
if necessary. There are little screws that are still open on top allowing
one screw to raise the motherboard so that it does not touch the computer
case while also connecting to a screw that holds the motherboard. This
process is very important to make sure your motherboard is not damaged. Make
sure you carefully place the motherboard into the case and use every
possible screw point provided by the motherboard.
- If you did not have the people at the computer store place the chip into
the motherboard and place the fan on top make sure you follow the exact
directions provided with the central processing unit and the central
processing unit fan. This is the one part of the process that you might want
to consult your locally owned computer store about if you have never placed
a chip on a motherboard before. If you are still not nervous enough to
consult a professional then read the instructions on the directions, every
process is different. Make sure that the power cable from the central
processing unit fan is plugged into the motherboard. You will also want to
connect the jumpers from the computer case to the motherboard. This is not
difficult simply read the documentation with the motherboard and connect the
cables to the right spot. These are your computer case speaker, power
switch, and hard drive activity lights.
- Remove the RAM from the protective antistatic bag and carefully place it
into the motherboard in the correct slot. Almost every motherboard is
clearly market with the primary RAM slot clearly identified. RAM is rather
large and only fits into one type of slot on the motherboard, so you do not
need to be worried just follow the directions in the motherboard booklet to
make sure you have properly locked the RAM in place. Make sure you do not
leave greasy fingerprints on the RAM this will cause trouble, simply make
sure your hands are dry and only touch the edges of the RAM.
- Now is the time to insert any video cards, network
interface cards, or any other specialized cards that require a Peripheral
Component Interconnect slot. I know you are surprised to find out that these
cards can only plug into one type of interface on the motherboard these are
the interface slots that allow you screw them into the case so that the back
end of the card is still accessible.
- Gather any disc drives, hard drives, and the floppy drive and check the
jumper settings on the back of them. This is really simple do not be afraid
make sure that the hard drive you want to put the operating system on is set
to master and that if you have a disc drive that can write disks it is set
set to the master setting as well. Everything else should be set to cable
select or slave. After you have configured the jumper settings make sure
that you install the drives in a logical fashion. You probably have three
IDE cable connection slots on the motherboard. Two bigger ones and one
smaller one for the floppy drive. You probably received ribbon cables with
your floppy, hard drive, disc drive, and motherboard. Look at the back of
your drives and figure out what size cable they need before you put the
drives in the case. Place the drives in the case so that the ribbon cable
can connect to the drives. The end with two connections relatively close
together is the one that should be connected to the derives and the end that
is all by itself should be connected to the motherboard.
- Make sure you have not accidentally plugged the computer case into a
power supply, because you should never have the power supply plugged into
the wall or the UPS while you are working on the computer. Find power supply
connections for all of the devices you have just installed, and then make
sure the power supply is connected to the motherboard. The power supply will
only have one cable that can connect to the motherboard and the connection
is generally near the RAM or the CPU.
- Take a moment to make sure that you have followed all the directions
that came with the motherboard, CPU, CPU fan, Hard Drive, and other devices
you have just installed. Make sure and check the connections of every device
to make sure everything is plugged in all the way and secure. Did you use at
least two screws on both sides of every device that connects to the case,
excluding the Peripheral Component Interconnect cards because they only use
one screw. Once you are sure everything is put together correctly go ahead
and close the case and screw it shut.
- Plug in the KVM (Keyboard, Video, and Mouse) to the correct interface
slots on the back of the computer case. Make sure they are plugged in
securely and that the monitor is completely secure.
- Connect the power cables from the power supply in the computer case and
from the monitor into to the slots on the UPS that are backed up by the
battery. No other devices but the monitor and computer case power supply
should be connected to the battery backup on the UPS. I have my alarm clock
connected to the batter backup on the UPS, but that only draws 9 volts of
power!
- Take a deep breath and make sure that you have followed all of the
directions. Did you really read all of the documentation that came with your
hardware? Think about how much money you spent on all of that computer
hardware. Now ask yourself again did you really read all of the
documentation that came with your hardware and carefully follow the
instructions and warnings. If you are confident in your abilities to follow
directions and you read all of the documentation, then plug the UPS into the
war and turn on the computer and monitor.
- Having problems read the next section of the guide about troubleshooting
your system configuration.

More fun than
you should be allowed to have right? Don’t panic we have all had problems
building computers here is a list of common problems and potential solutions.
Please make sure that you have read all documentation related to your specific
hardware configuration.
- You push the power button and nothing happens.
- Did you remember to correctly jumper the power switch cable from the
computer case to the motherboard?
- Is the UPS turned on and the lights are correctly flashing in the
front?
- Have you checked the power supply switch on the back of the computer
case and make sure it is on?
- You can hear the computer case turn on and see the lights, but nothing
happens with the monitor.
- Did you check the back of the monitor to see if it has a power switch?
- Is the power cable correctly plugged into both the monitor and the
UPS?
- If your computer has both an on board graphics card and an AGP
graphics card that you installed did you try testing the other connection?
- Can you see the power light on the monitor turn on?
