Do you know how much current the nano's are likely to take? The EPIA-M ones 
I was told needed 3A at 12V to the DC-ATX converter.

6W idle (just the board/CPU), which is about 0.5A, to 36W at full load 
assuming a notebook HD and slim optical drive as well - I found an ITX power 
configurator but forgot the URL. What that said was 24W at full load just for 
the board, which is 2A. Give it 3A to be on the safe side (I'll be using 
CFIDE for local storage on the nodes, HDD or network storage for the master 
node/output) per node, that's 36W per node. A 70A/12V bench PSU would be just 
dandy for upwards of 24 nodes.
Failing that, a truck battery.

There's some on one of my servers hidden away:
http://mail.7of9b.org/~chris/pictures/2003-09-09/small-100_0127.JPG - 
without any HDD
http://mail.7of9b.org/~chris/pictures/2003-10-19/small-100_0276.JPG - stuck 
in the rack in HEX - prob why a PSU/MB failed ;)
(there's prob some more of it somewhere but I doubt any of the insides)

nice setup... I'm going for the more pullable module variety.

I've had a WRAP.1E sat here a couple of months I wanted to get setup as a 
router/firewall... hope your project gets finished a bit quicker than mine 
take ;)

heeh... we shall see :)
Incidentally, there is a liveCD firewall you might be interested in:

Apparently this'll run on a 486(!!), tho it does also support wireless.
