Silent HA PC

["Bricknell, Tony" <tony.bricknell@xxxxxxxxxxxxxxxxxxx>]

I'm after an (ideally) silent PC for use as:

p2p file sharing,
possible audio/video server,
HA - haven't decided how/what, but with a PC on 24/7 it would be criminal
not to put it to HA use.
Outward facing web-interface to possibly TiVo, security cameras, Comfort,
...?
Remote display for occasional use in the kitchen (on-line food shopping,
etc)

Whilst I'm quite capable of spec'ing a machine to do these tasks, my
knowledge dries up when looking for a "fanless" solution.  I
think that an
EPIA mobo will struggle with serving multiple audio/video/whatever, so I've
started looking at a "Shuttle" sized unit.  May have to go bigger
to
comfortably fit/keep cool a couple of 160GB drives...?

I presume Intel run cooler than AMD?  Any recommendations for cases that
can
be easily modded to provide passive cooling on everything?

I've checked out www.quietpc.com but even their "fanless CPU
coolers" rely
on the PSU fan to maintain airflow :o(

TIA,
Tony
