These parts are brand new, a P4 3.0ghz C with hyperthreading. The motherboard is a very stable intel 865GBFL, with onboard...everything (sound, LAN, video, SATA). Basically it's loaded. asking only $450 now.. You'd be paying about 600 for it anywhere else. If you need any other parts I could hook you up no probz. (case, video card, other hardware). Full warranty coverage for a year. Also got an athlon XP 2100+ and 512mb DDR PC2700 ram for sale for 160 (only CPU and ram). need anything else? ask.
