Picture of DIY PC Component Selection

Do you remember when you were a kid, tearing things apart to figure out how they work? Well, this Lazy Old Geek does. I was a Nerd before I became a Geek. Actually, I still tear things apart to see how they work.
Now that I'm older, I thought, how about figuring out how some thing works by putting it together. And I am talking about a computer.

Now there are a lot of good Instructables on how to build a computer.
But perusing through them, I noticed a topic that is not covered very well: component selection, choosing parts that will work together. So I will guide you in the selection process and hopefully give you some insight on how computers work. Even if you don't want to build a PC, someday you might want to fix or upgrade your PC. This Instructable should help you do that also.

Skip this: Since you are reading this, I assume that you are fairly knowledgeable in using a computer. But what do you do if/when your computer stops working. Well, I know many of you have a GoTo guy/gal that you call up to fix it. Well, this GoTo person is probably a GEEK. So do you want to become a GEEK? No, I don't think so. But maybe you would like to communicate better with your GEEK.
Totally Irrelevant: GoTo is also a programming command that was often in early versions of Basic. In early computing days, there was a big division between Basic programmers and C programmers. C programmers always thought Basic programmers weren't really computer programmers because they used the 'GoTo' statement. There is a little bit of truth to that. I've always been more of a Basic programmer, than a C or C++ programmer.

So why build your own PC? Here are some of my excuses, uh, reasons:
Save money. The truth is I don’t really need a new PC.
Design it the way I want it.
Put in expandability/upgradeability that I might want.
Challenge to see if I could do it.
No bloatware (probably). Bloatware is all the free software most manufacturers put on their production PCs that’s hard to get rid of.
Out of boredom.

Incompatibility. I will try to address mostly of these issues.
What if it doesn’t work?

So here is my list of essential components:
Video card(?)
Hard drives
Power supply
DVD player

A phillips screwdriver
A brain

Internet searching
Willingness to learn

If you read through all of this Instructable, you may not believe it but most of these components are standardized. Motherboards come in a few standardized sizes and layouts. Memory modules for desktops are the same size and fit in the same sockets. Power supplies are physically about the same size and have standard mounting holes. Hard drives and DVD players fit into a couple of different standard slots and have only a couple of different interfaces. Power supplies have pretty much standard connectors.

You should do something to those cables. Looks horrible mess.

Yes, I should. Actually, since I made this, I built another PC and had to swap the power supplies as I had a compatibility issue. I'm trying to do cable management better but I am OLD and LAZY so mostly just make sure the cables are away from the fans.

Im reading this after i built my computer and i find building a computer a ton better because u do have alot more capabilities and not all that crap u get from the manufacturer taking up space on your hard drive and its also fun getting it all up and running
