3g ram
ati raedon x600 w/ 256 ram
3.0 ghz p4 w/ hypertheading

Got it for about 700 dollars from dell a couple years go, just added 2g of ram.

Runs 5 wows in windowed mode, none minimized, at 3-30 fps. Some resized to be smaller though. Not suggested for heavy pvp, but little to no problems so far for pve. AHK to pass keys. All from one wow directory with very little HD space left over(currently 6.2GB).
