Inspiron 530 Desktop
 - 2.0Ghz C2D CPU
 - 4GB ram
 - 320GB hdd
 - dual layer DVD burner
 - onboard LAN, video, sound, etc 
Comes with a 17" widescreen LCD and a decent printer.  All for $579.  
Bought it for my kids who have been clamoring for another desktop (primarily to play WoW on).  
  Ubuntu is installing right now.  I had a decent graphics card lying around...so WoW should be quite playable for them under Wine. 
It came with the "Home Preminum" version of 
the nasty, if that matters to anyone.
