Re: computer rebuild
+1 for the WB Blacks.
The build Fat.Clown posted is a good one, but you will need a new OS. Go with the mobo, CPU, and RAM. Grab a new WD Black hard drive and a Windows 7 Home Premium OEM. The onboard 4250 will be a lot better than the 6100 you are currently using. That will put you at around $365. You can toss in a SATA DVD burner for around 20-25.
Later on you will probably want to add a graphics card. You will need to replace your power supply when you do, so plan on $150 minimum at that time.
