This is an amazing board for Linux: optionally, it works with a normal 'brick' laptop charger, through an AC connector. No PSU! Zero noise from the source!
I'm using a 60W notebook charger, and coupled the motherboard with an Atlhon 5350 Quad-core and a 750GB 7200rpm 2,5" disk (WD Black). The 60W is more than enough for all this!
