I've tested a bunch of 'business-grade' desktops around my office, and they all run 40-60 watts during normal use (not including monitor) with peak power at boot time up to 70-80 watts. This includes some P4s with lots of memory, CD-RWs, etc. (The one exception is an AMD Duron system; it seems that the AMD processors are uniformly power-hungry.) I'm told that Mini-ITX systems pull around 20w, if you're serious about low power: I'm eyeing one of those for my office mail server. Any decent laptop should be under 30 watts. Tim
