Well plenty of people have replied since so no more to add   , except 
you may well win on watts per kilogram   :)

No it really is a desktop, AMD 3500+ dual core, onboard graphics, but 
not including the screen.

but seriously its worth measuring if you want to control your energy 
use. I measured electricity use of my  work computer, a standard dell 
machine. Consumption while in (Windows) shutdown mode is one third of 
'in use' consumption and it is in use for about one quarter of the time. 
  So if I don't turn it off at the mains (wall) socket it uses as much 
electricity  while not in use as while in use.  Getting anyone to take 
notice in a corporate environment is impossible but that's another story 
        sigh!
