One justification for this for me would be power consumption. 
Currently I'm running SS on a P4 system, very power hungry.  I'd still
be using it all day long, but at night I could shut it off and let a
low-power SS server run so that it could wake me up in the morning (I
use an SB2 as an alarm clock).

There are lots of peak power calculators out there, but I'm looking for
idle power figures.  Unfortunately these are very hard to find.    The
best one I saw was this:
http://www.complang.tuwien.ac.at/anton/computer-power-consumption.html

I assumed my P4 system was like his P4 system in the Boxes section near
the bottom, but mine is newer/faster and has 3 discs, so I
conservatively assumed 80 W idle.  A fanless VIA system would be like
the last entry in his Boxes section, 16 W, but with one disc at 7.3 W
idle, see here:
http://www.storagereview.com/articles/200511/SP2504C_6.html.  That's a
savings of 56.7 W.  Now I'd be saving this for 14 h/day (my P4 system
would still be running during the day) so that's 0.79 kWh/day.  At our
power prices of $0.058/kWh, that's only $16.80 per year!  Unfortunately
this hardly justifies spending $300 just for the motherboard...

Amazingly, even with the monitor on ~8 h/day, assuming my 17" CRT draws
60 W, the power costs for my P4 box for an entire year is only $47.42.

I do like saving power but I'm also an engineer and I know an
uneconomical project when I see one.

I may take your advice and use one of my unused older systems though. 
This would save manufacturing a new one - I've already saved every
computer I've come across from the landfill.  I have a secondary PC
with a 1.2 GHz AMD Duron - I was going to use this in the basement for
model railroad use.  I still have my first PC with an AMD K6-2 400 MHz
processor, and I built a P166 from discarded parts (which ran
ClarkConnect 2.2 although quite slowly).  My most recent find is a P4A
system, unfortunately with the pricey RDRAM gone.  However, ADDING
another PC that's not plugged in now would just serve to increase my
power consumption over what I have right now.  I'd have to use it to
replace what I'm currently using, and even then the power savings are
small.

It's too bad.  Much like gasoline, although electricity is expensive,
it's just not expensive enough to justify spending that much cash.
