It's alittle more than what I really wanted to spend but still reasonable. I'm going to use one of my half-dozen hard drives I have to build this rig and swap out my current 485W PSU for a cheaper 430W I just bought for $20 after rebate. If I had just stuck to upgrading the guts instead of building a complete box, then it would have just been the cost of the CPU, mobo, RAM, and video card. That would have come out to be around $645.29.

EDIT: I finally managed to snag myself a 8800 GT. Price totals have been updated accordingly.
