I'm looking to build a Vista ready computer, but need advice on parts. Looking for a AMD Athlon 64x2 processor, Nvidia PCI-E x16 graphics card, 2GB ram, and etc. I already have a primary 30gb HD w/ a 120gb secondary HD, dvdrw lightscribe drive, and a decent case. I'm looking to build this PC for around $400.00 or less. Is it possible? Help me out! Link me parts! Thanks alot!
