STEP 1 : Purchase/Collect The Components

Often this is the one step that takes the most time and consideration. Which parts do I buy? Which are best?

There is everything you need to build your PC on this website, if you need something specific which you can’t find then please ask. You could go to a computer retail shop in your area to browse although you will pay a more than you will here. Sometimes, a lot more. Also, due to the sheer volume of people they see every day, some of the "support specialists" don't always listen to your concerns and start jumping to conclusions on what you need or what the problem is. Some of them take pride that they can give you a technical answer in two seconds and make themselves look smart, even though what they just said is probably wrong. If you walk in and say your computer keeps crashing and he insists you need a new motherboard and CPU to fix it, start running.

The hardware we sell is often retail packaged from the manufacturer. We may also sell OEM hardware, which usually comes wrapped in nothing but a static bag and is accompanied with very little documentation. You will need to be the judge on this type of hardware. If you feel you need the documentation, you should not buy OEM hardware. The bottom line here is to know your stuff. The PC sales industry is occupied by many who WILL take advantage of your lack of knowledge to make a sale but with a little time spent learning what is what, we hope you will be pleased with the results you have, not only financially but from self-satisfaction too.

Now, let us go through each type of hardware:

Case : Make sure you buy a case which will fit into the space you intend to place it. This is where you decide between a desktop or a tower case. Allow room for expandability; spare drive bays, ample room to work inside. Make sure it has a power supply. Is the case clean? Pay attention to the form factor: AT or ATX. Almost all newer motherboards are using the ATX form factor, so if you have an old case lying around, chances are a new board won't fit in it. If you do a lot of upgrading, you should get a case that is designed with this in mind, such as easily removed motherboard mounting plates, drive racks, etc. Things like the turbo switch and keylock are ancient technology, so pay no mind to having them. Try to have the buttons such as power and reset recessed, so that if you keep the case under the desk you won't accidentally kick the thing and reset it. Also, check the sturdiness of the case. Some cheaper cases are actually quite flimsy inside. Pay attention to how the case comes apart. Depending on the design, the screwless type is very user friendly. It's easier to work with a case that does not come apart in many pieces.

If you will be running a high-end processor in the case, pay attention to the cooling aspects of the box. It’s nice when cases come with case fans included, but if they do not, you should make sure the case is designed to allow them. You should have an unobstructed air hole in the front of the case for a front-mounted case fan, with some method of air flow from the rear of the case as well. Many power supplies also aid in cooling by having bottom-mounted fans that suck air from the inside of the case and blow it out the back through the power unit. And, along this line, pay attention to the wattage rating of the power supply included with the case. If you will be running either a large amount of hardware or fairly high-end hardware in this case, get a good strong power supply. I, not too long ago, upgraded my own PC and shortly thereafter had this mysterious odour of burning plastic in the office. Using the good old’ sniffer, I found that it was the power supply burning up. Right about the time I tracked it down, the whole PC went poof! Gone and could not turn it on again. I took out the 250W power supply and installed a solid 400W power supply and the PC has been running strong ever since. The PC ran great fairly loaded with a Pentium 3 450 MHz, but putting a new board and an AMD 1.3 GHz Thunderbird in there drove it batty. So, keep this in mind.

As far as brands go, there are many good manufacturers out there. We've even seen some I-MAC looking cases that are semi-translucent. If you want a futuristic look, these may interest you. All aluminum cases are now started to catch on. If you don't mind spending a little more, you may want to take a look at the quality cases made by Lian-Li. If you’re into modified cases, you can get them pre-modified with viewing holes and everything. Or, if you’re so inclined, you can grab a nice case and do your own mods to it. For some reason, though, I’ve never been keen on tearing huge holes into my PCs, but maybe it’s just me. There are plenty of cases on the website to choose from.

Motherboard : Almost everyone knows that the motherboard is the most important component of your computer. At one point or another, every other component connects to the motherboard. Keep in mind that your motherboard choice controls your future upgrade paths. Want to upgrade you memory? You first have to check and see what type your motherboard will take, and how much it will support. Want that new video card? Your motherboard will need an AGP slot. Get the point? If you choose the wrong motherboard in the beginning, you may find yourself having to buy a different one down the road to support some other upgrade. Today's motherboards are a lot more sophisticated than the one's in the 486 days. If you are used to these older systems, you will need to come up to speed on the latest boards. Where you once needed an IDE controller card, the connectors are now built right on the motherboard. USB was once an option - now it is integrated on every board. Some boards go all the way, offering built on SCSI controllers, 10/100 Ethernet support, onboard video and sound, etc. Buying a motherboard is a tradeoff - you need to know what you want and then pick that board which has the best combination of features for you. Bear in mind the old adage - sometimes it is better to buy what you will eventually end up with anyway.

There are really three levels of motherboards. Of course this is a generalization, but it’s accurate enough.

Bare-bone boards. These are the types of boards you usually get if you are not into PC hardware and don't want to deal with frustrations. You just want to build it and turn it on. These boards have built in sound and video, and sometimes other gizmos too, like a modem. They don't usually overclock well and don't have a wide range of CPU support. These boards are comparatively inexpensive. Many times, pre-built PCs come with these types of boards, and this is one of the reasons you should be following this tutorial. If you’re going to bother building your own PC, get a board that’s worth your time. This isn’t it.
Secondly, we have the level of board most commonly used. These boards come with a single CPU slot, EIDE controller, etc. Most don't have built in video, although more of them have built-in sound. This is fine, as long as it is easily disabled. They support a wide range of processors, and with more voltage and multiplier settings, they are more overclocking friendly. Some of these boards offer RAID capability. With the proper amount of PCI slots, these boards are great.
Thirdly, you have the beasts which most of us cannot afford. These are the dual processor boards, often with built on NIC and SCSI, and a lot of PCI slots. These are more for NT workstations than your desktop PC.

Some things you want to bear in mind:

Board Layout - A lot of people don't consider where everything is placed on the motherboard, but it is important. Is there a big capacitor right near the CPU slot, blocking where your CPU fan will go? Is there a bunch of crap that will block your full-length PCI card from fitting? Are the memory slows in a position where you’d need to remove the floppy drive to get at I them? You need to know roughly what you will be plugging into this board and know if anything will get in the way. This also depends to a degree on the size of the case you are using. Trying to cram a larger board, like an Abit board, into a mini-tower is asking for trouble.
Slots - If we had our way, we'd have a motherboard with 20 PCI slots so we could run everything in the world. Unfortunately, this doesn't exist. So, you need to pay attention to how many PCI slots a motherboard has. For most of us the standard 4 or 5 PCI slots will be fine. Be careful, you can easily fill all your slots. Make sure the board has an AGP slot and if necessary, ISA or CNR slots.
Manuals - Believe me, you'll regret it if you don't think ahead and get a board with a good manual. If you purchase a no-name board, you'll probably get stuck with a manual that was written in Taiwanese or English you think a monkey would write. A lot of times, you'll find a pile of addendums added to the manual. They couldn't get it right the first time?! Make sure to look at the manual for your board and make sure you can understand it. Most well known brands have decent manuals. Asus, Abit, FIC, Tyan, Shuttle and a few others come with nice manuals. Another thing to keep in mind is that the better known manufacturers often have nice web sites, and you can get support info there, too. If you don’t know who the manufacturer is, of their website is utterly useless, think twice about using the board. Otherwise, you’ll be trying to email people like me asking who made it and I’ll probably not even reply.
Form Factor - Unless you would die without that older server case you are using, I would recommend going with the ATX form factor. ATX integrates all of the connectors, whereas with AT, you have to plug all of that crap in. AT boards use that big DIN keyboard connector which is a relic.
Chipset - The chipset is the hub of your motherboard. You need to pay strong attention to what chipset a motherboard has before you purchase it. The chipset is fully responsible for what hardware your motherboard will support now and in the future. It controls everything. If your motherboard won't support ATA-100, AGP 4x, etc. blame the chipset. There are many chipsets out there, and this tutorial is not the place to address them all. But, doing your research on this site and others, as well as observing the specs of the chipset itself before you buy it, will be beneficial.
Hardware Support - This one is really a no-brainer, but bears mentioning anyway due to its obvious importance. Pay attention to the specs to make sure that the board will support the hardware you would like to use. If possible, allow room for expandability beyond what you will be using as this will ensure you can use the board for awhile. If there are embedded components such as sound or video, this is fine as long we you are able to disable it easily. Unless you like that all-in-one thing, you’ll find you want to eventually put something better in there and you don’t want it conflicting with the built-in components.
Reviews - Finally, before purchasing any motherboard, find out what others think of it. You can rest assured that if there is any nagging annoyance with any motherboard you are thinking about buying that several people have noticed it and have posted all over the internet about it. Check out hardware review sites. I'm sure you all know where to go for those. Also check out Usenet Newsgroups.

Processor :

Processors come in three basic levels:

Low End - This group is made up of the people that may be starting just starting their own business, and need a computer to print letters, invoices, and other business related things. Most standard business software will run just fine on these processors. £30-60
Average - This group of processors encompasses the bulk of the chips being sold right now. These processors zip at business software, but, depending on the speed and other things, also zip reasonably well at image editing or gaming. These include the Pentium 4’s and the Athlon XP’s. £60-£120
High End - This group is the usually the company that's very competitive, on the leading edge of profitability, needs a high end processor for CAD, or just has a lot of money to burn. Pentium 4 3GHz + Athlon 64 bits. £200 +

Which CPU you need for a new system is a matter of personal choice. And, on this note, keep in mind that all processors need cooling. Most retail-boxed processors come with fans included or already attached. But, if not, or if you’re getting an OEM processor, make sure to get a good fan. Make sure the fan is of the ball bearing variety and not one of those cheap sleeve bearing fans. Make sure it is rated for your processor, as some fans look fine when you look at them, but wouldn’t help a high speed processor do anything but boil itself to death. Also, and this is not usually an issue, it is nice when the fan gets it power from the CPU_FAN power 3-pin plug on the motherboard rather than take up a plug from your power supply. If you are dealing with older hardware here, you may have the heat sink separate from the fan. In this case, you’ll want to make sure the heat sink has a way of attaching to the processor, either by clips or with heat sink compound.

Memory:

Memory is a big part of your machine, so get the good stuff. A lot of people get really confused when it comes to memory, and it’s really not necessary. Some memory manufacturers will help you find compatible memory for your motherboard on their websites. One such company is Crucial Technology. In most cases, standard non-parity, non-ECC memory will work just fine. Many boards today are still using SDRAM, although DDR-DRAM has really caught on and is a lot faster. In short, though, memory is not a huge issue and just buy what your motherboard requires. And, with today’s prices, buy lots of it. Operating systems themselves require large amounts of memory. Windows XP’s bare minimum requirement is 128MB of RAM. So, give yourself ample breathing room and don’t try to save a few measly bucks by not getting enough memory. DDR memory is supplied in different speeds PC2100 PC2700 and PC3200. It’s recommended to buy the quickest your motherboard will support as it costs so little extra and can really increase the overall speed of the computer. Some motherboards support dual channel memory which doubles the speed if two identical sticks are fitted.

Video Card:

There are just tons of video cards out there to choose from, all saying they're the best and sporting snazzy graphics on the boxes to grab your attention in the store. Let me give you some general pointers:

Where it used to be we all used 2 MB cards and thought you were a gaming nerd if using a 4 MB card, all graphics cards today have a lot more- usually 64 MB or higher. Get it. It won't cost that much. Likewise, AGP4x or 8x is now the standard, so unless you're using a relic motherboard without an AGP slot, get an AGP video card. As for power, consider what you'll be doing with the PC. If you're doing mostly business and internet and the occasional game, then you don't need a super-duper gaming card. A card with decent 3D and good 2D power is better for you. Most video cards on the market today are pretty decent at 3D and kick-ass at 2D. 2D really does not require all that much out of a video card. Watch the reviews to get viewpoints on different manufacturers. Some cards come with TV-out channels, video-in, or even TV tuners. This is great stuff, and if you can afford it, go for it. I would say, in general, though, that do-everything cards usually sacrifice performance tweaks, so if you’re trying to build an all-around kick-ass system here that pumps pixels so hard you’ll drool, get a card that does that with authority and don’t worry about the TV. Hell, you can buy a TV cheaper than some of those video cards. Make sure whatever you get is matched to your monitor. There is no sense in buying a cutting edge video card with killer refresh rates if you're using a clunker monitor that can't do it.

Removable Storage:

All PC’s have some form of removable storage, even if it’s only a floppy disk drive. In the case of a floppy, there’s really nothing much to know about them. Just buy one that looks alright and works. And, don’t even think about putting a 5.25 floppy drive in your PC. A lot of PCs now boast more advanced media such as ZIP drives or maybe an LS-120. These can be useful, given that 1.44MB for a floppy is really barely anything. Plus, they are slow as hell. Beyond these drives, though, the CD-R/CD-RW drives are the real craze right now…and for good reason. If you want a drive where you can perform backups and share data with friends without really worrying about capacity issues, invest in a CD burner. They are pretty fast now, and companies like Liteon and LG offer drives with Smart-Burn technology that will virtually guarantee you never mess up a burning session by doing something else on the PC at the same time.

Hard Drive:

Make sure it looks good. Always buy new, in my opinion. And make sure it has a manual, or at the very least, a jumper diagram imprinted on the drive itself. For price and compatibility, I'd stick with IDE. With IDE, though, make sure the drive is UDMA. Most likely, your motherboard supports ATA-33,66100.or133 So, you may want to get a drive that can pump that hard. Get a drive with a decent rotation speed. 5400 RPM drives are slow. 7200 RPM is better, and higher RPM drives even better. The really fast drives, though, may require a hard drive cooler, so unless you are willing to mess with that, get a drive with a good balance of speed and temperature. If speed is your biggest concern, go for the SCSI interface. Keep in mind that with SCSI you will have to purchase the additional hardware necessary for the SCSI bus. Also, get the largest drive you can afford. You’ll be surprised how fast you can fill up a hard drive, depending on what you do with your PC. Large volume drives are dirt cheap now, so get yourself a biggie.

Sound Card : An absolute necessity in today's PC world. There are tons of available cards out there, but I recommend the name brand again. I've tried some of the various cheaper clones and had my share of driver issues with them. Read the reviews, as there are a lot of sound cards out there with special features. Some cards pimp special sound algorithms that are supposed to enhance the sound. Some of these suck, but others really improve the sound. Some cards, like the upper-end Creative Labs cards, have extensions with all sorts of inputs and things that attach to the sound card and expand the capabilities. These are not usually important unless you’re into sound mixing or audio-video editing. Make sure the card has 4-channel support, because this really makes the PC sound great if you have enough speakers. With the card, you must get speakers. You can spend a lot on speakers, but I recommend at least a 3-piece system (with a sub). You'll appreciate the deeper base response and overall sound.

CD-ROM/DVD : Make sure it has a driver installation disk (almost all retail units do). You will need to get this drive working so that you can install the operating system. These drives are very inexpensive now, get a fast one: 40X or faster. Make sure it is ATAPI compatible IDE. Some drives look like IDE drives, although they really use a proprietary interface, such as that used on some older Creative multimedia kits. If you're buying new, you won't find this in the stores anymore, so don't worry. If you want more than a simple CD-ROM, get yourself a DVD player. These drives are not much more than a regular CD-ROM and are backward-compatible with CD-ROMS, so they serve all purposes. Then, with a good DVD software player like PowerDVD or WinDVD you can watch movies or use DVD software on your PC.

Keyboard & Mouse : Rather self-explanatory. Make sure the keyboard connector fits into the plug on the motherboard, otherwise you may need an adapter. Most new boards use a PS/2 connector for the keyboard. Make sure the mouse works. And choose the right kind for your system: serial or PS/2. If you like, you can get fancy "Natural Keyboards", which are basically regular keyboards that are bent in the middle. It takes a while to get used to them, but they are nice. You can also get mice with various gizmos such as scroll wheels, roller-balls, etc. Also, you can check out optical mice, without balls which don’t require cleaning.

Drive cables : Make sure you have all cables for connecting the hard drive, floppy drive, and CD-ROM to the I/O on the motherboard or I/O card. These cables usually are supplied with the motherboard or drive itself, but not always, and sometimes not in the quantity you need. Make sure they are long enough. Inspect for damage, such as ripped wires or something. Also, keep in mind that ATA/66-100 drives must have an 80-wire IDE cable. It's the same width as the norm, but each wire is thinner, so they cram more wires into the cable. If you’re paying special attention to cooling issues, you may choose to get rounded data cables. These are nice as they tidy up the inside of your case and allow cleaner air flow than would a case crammed with a bunch of wide, gray ribbon cables that often get in the way.

Audio Cable : Usually supplied with the CD-ROM, it connects your CD-ROM to your sound card directly.

Screws : Makes sure you have enough screws. Usually an ample amount is supplied with your case. Make sure the screws are the right size. There are different sizes used for connecting card than for connecting drives, and if you try using a large screw on the drive, you'll crack the drive.

System Disk: Make sure you have a system disk setup and ready to use. You can make one for whatever operating system you plan on using. If you have another machine already running, use it to make a system disk. Hopefully you are using Windows 98 or better, since it makes CD-ROM setup later in this tutorial much easier.

That was a brief overview of the hardware scene for you and hopefully it serves as some advice for collecting parts to build your PC. There is no way I can cover all brands of make any solid recommendations as to manufacturer in this tutorial, so much of that research would need to be done separately.
