To start off, you'll need nothing more than some money to burn.
So lets go!
Well, it would be hard to select a computer without a case. You'll find some good cases as well as all other computer software at www.newegg.com.
Cases come in many varieties and it's hard to pick. The case has little impact on performance, so pick it on personal preference. If the case does not come with a Power supply, make sure to pick one up.
If you plan on doing word processing or something similar to that 200-300 Watts should be sufficient while a gaming computer might want 500 Watts.
Ok, on to the motherboard.
There are two main options you can go with, AMD or Intel. You might want to go with AMD, as they currently offer affordable 64 bit technology. Make sure the motherboard you pick has "Socket 939", so it will be compatible with the latest proccesors. If you have a lot of money to burn, go pick a motherboard that has SLi enabled which allows two video cards to operate in tandem.
While selecting a processor, keep in mind that your cpu must be compatable with your motherboard. Do this by ensuring that they both use the same socket.
Keep in mind with 64 bit proccesor speed cannot be directly compared to pentium 4s.
More to come later!
