I just put this box together using NewEgg.com and put most of my money into the big 3: CPU, RAM, and video card. For a$100 or two more, the video card could have been a little better, but I prefer the single-slot, low power consumption of this one. This PC runs very quiet and cool (cpu at 85 deg F idle, about 100-105 deg F gaming).

I could have saved $218 if I would have settled for the 3000 (1.8GHz) cpu and then tried to overclock it to 2.4GHz.
I could have saved $200 if I would have settled for 2x512MB of value RAM, but Aces High 2 uses more than 1.2GB when I play it on this box

I could have saved $20 on the hard drives, but it was a small cost for top of the line SATA2 performance paired in a RAID 0 configuration.
I could have saved $20 on the motherboard, but the cheaper ones didn't have SATA2 (normal SATA has half the potential performance of SATA2).
The DVD burner was actually lower than the local CompUSA sale/rebate pricing.
Taking into account all of the above, I could have spent only $1050, but the extra money ensures I won't want or need upgrades for awhile...
Other than another 2GB of RAM to fill in the empty slots and eventually a 512MB RAM video card with twice the pipelines of this one
