Hello Michael,

The keyword I read here is "installation", so the first three things on your
list should be reliability, reliability and reliability. Nobody wants to see
"This installation is out of order", and you don't want people seeing that
right next to your name while you are 1000 miles away working on another
project and uncontactable. Incidently - I saw a Nat West bank cashpoint
yesterday with a "Win32 DLL missing" error - the thought of banking machines
using Windows sends a shiver down my spine!

Closely connected to this is remote access, because this is your way
into the system to reset or repair it when you are unable to be physically

Basically, the system should be designed like a server not a desktop. You will
want an SSH shell, thttpd/boa type webserver to give you a page of easy to
access stats, (uptime, CPU usage, memory etc). Stock Debian is probably the
best all round OS for this application. The motherboard should be set up to 
reboot on shutdown (power into last state) so you can do a remote reset.

I think the best motherboards for installations are mini ITX 2.4GHz types.
(Don't buy them from mini-itx.com if you ever want to see your purchase!)
These can be practically silent with the fansink cooling, or if you want to go
down to 1GHz (which can deliver a lot of audio) then you can go to a completely
silent fanless system (perfect for small galleries). A wall mount case can be
bolted to the underside of a desk as well as on a wall so your hardware 
doesn't go walkies when unattended. 

Careful with cases, make sure there's enough slot room for any cards you
want to add with mini ITX systems and make sure the PSU is rated high enough
for the cards too (it probably is, even with the smallest wattage).

best regards,
