I built this system a couple of weeks ago and am way more than happy with it. Got everything through Newegg.

This system has 2 gig of memory and a striped SATA RAID Array (didn't show the second hard drive above).
You could save some bucks by:
Reducing RAM to one Gig:
-$139 1 Gig Memory
Not getting a fancy Heatsink (the chip ships with one).
-$29.99 Fan/Heatsink
Not going with the Lian Li Case, I think you can get one for about 45 bucks or so.
-$45.00 Case
Winds up to be
$1496.42 plus tax and shipping.
I love this box so far. The game looks completely different. Getting good framerates and haven't seen a stutter yet.
I'm not a computer guru but the thing went together without a wrinkle.
