Low power PC, AMD or Intel?

[OverDamage]

I already have an uber gaming PC with full custom water cooling and an E6600 OCed to 3.6Ghz. Now I'm looking to build a small PC for 24/7 folding/torrents/voip/file storage.

The main concern with this build will be power. I'm in the Air Force and currently live on base in the dorms. Given this I have free electricity, but I'm willing to bet only 1 circuit breaker for my room. I want this PC to be low power to prevent poping the breaker if I was to, say, make popcorn while playing crysis with all the lights on and jabbing a fork into the wall socket(minus that last bit). Mainly I'd like to hear opinions on AMD vs Intel power use and what CPU would be best for my application.

It say the AMD low power Brisbanes. Because they are cheap and seem to be what youre lookin for

I don't think this is quite an answer, but why not build a system around a laptop board if power is the big issue (or just get a cheap refurb laptop on ebay - you'll get battery backup for free)? Perhaps your question can be rephrased to what is the lowest power consumption for the tasks I intend to run?

I've seen laptop board + proc for less than $100 on ebay, get interfaces at dealextreme and you are set. You'll save $ on build and save on electricity.
