Here are a few pointers for a system setup.
First either select the CPU or Motherboard. They have to be compatable!
The CPU socket has to match the motherboard! Select the speed of the CPU.
CPU heatsink and fan has to match the type of socket the MB has. A good quality HS is always best. Apply a very thin coat of HS paste prior to installing!
Select the memory that the Motherboard supports.(Manual list type etc).
Suggest 4 g as you probably will want all the speed you can get later.
Select a very good fast video card that is compatable with the MB. There are quite a few different quality cards available. It is best to get a good one for what you are intending to use the comp. for.
The power supply should be aroung 400 watt or larger.
Most hard drives will work. If a large one of 100g or better, maybe partition it prior to installing Operating System. Suggest the partition for the OS should be approx. 40 to 60 gig. All programs normally installed on the computer goes on the C drive! (Unless you have another drive and install programs on it) As the OS is somewhere arount 25 g or better, you will need the extra space for daily use.
This info is typical and your needs will have to be reasearched to see what type and numbers you already have. READ ALL THE LITERATURE that came with the equipment prior to making your final decision.
Hopefully this will help in some small way. It is only a guide, as everything is so variable. Good luck
