Here's what I got from eCollegePC, prices and all. Draclvr (I think it was) said I might have gone overboard on the power supply and the 8 gigabytes of RAM, but I thought, what the heck, this is the last computer I'll be able to buy for a long time. <g>
I definitely wanted and got the best video card I could afford. You'll see at the bottom that I got two extra case fans. It all came out to just a little over the most you want to pay.
