It's a Dell Vostro 200 business computer; I put that biohazard sticker on the side for kicks.
Anyway, specs:
2.33 GHz 4 MB L2 Core2Duo
80 GB HDD (320 GB external on top)
2 GB RAM
256 MB nVidia 8600GT
XP SP2
I zip tied a pair of high powered hard drive coolers on the outside of my case, as there is a vent/grille on that side. Moment I plug it in with my external AC-to-molex adapter, it's like a plane taking off; temperatures drop 10 degrees in 10 seconds!
