Well, I've forgotten to mention that I didn't substract all peripheral 
devices. My new calculations (idle, nothing but the big black box under my 
desk): Linux 137W, Win 114W (20% or 18EUR / 20$ p.a.).

It seems I can't disable my onboard WLAN completely and while Win deactivates 
it because I don't provide drivers, Linux gives it some power although no 
software is accessing it. 

By the way: Maximum output while testing with 3DMark 2006: 219W. I wonder why 
I had to buy a 400W power supply...
