A Zotac ION-AU, dual core 330, using an external power brick, 9400M 
chipset and one 2.5" hard drive spiked at 35w during boot and ran at 27 
basically whatever I played. That without any suspend or screensaver 
etc. That included High Def playback.

Could probably get a little better with the video stuff turned down.


         Please let me know if anything I say offends you.
          I may wish to offend you again in the future.
