Again on power consumption, I used to run my web server (ubuntu 10.04lts) on a fanless mini-itx board, about 30 or so watts- now it's on a BeagleBone arm board about the size of a credit card, still running ubuntu , consumption is down to a whole 2 watts. I have it running ntp and serving time to the rest of my home network. Even 'er indoors thinks that sort of power consumption is acceptable!
