What's your current system? If it's not too old (pre ATX case) and has a functional HD, you probably just need a new motherboard, AMD processor 2500 barton (not hard to get a safe overclock to 3.2 levels - at least for me, YMMV!), and a $100 to $150 video card - maybe even gety by with less. Total about $300 - $450
