I'm kinda building a new computer....I have a 250GB hard drive which I'm reusing, a Radeon 9250 Video card and a Sound Blaster Audigy 2 sound card. I also have a CD burner which I'm reusing. Basically, I need advice on a new motherboard, processor, RAM, DVD Burner, and case for it all. I know the stuff I have now isn't great, but I need to keep this around the 400 dollar range...if that's only possible by leaving out a DVD burner and RAM, that's fine. I need this to be a fast computer...I'm upgrading from a 1.8Ghz Pentium 4 so most stuff should be an improvement. Thanks everyone!
