From the few details of your post, this system will be moderate to high end, as far as the cost for motherboard cpu and 1 gig of ram, Ill average at 350 for reasonably high end parts. I built a great system last year for my parents, had the tower, a cdrw drive and power scource, cost 600, parts suplied from a great suplier; mind you, this system is faily good.
