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!
