Not that big of a problem. Limey Linux now supports the D525MW.

Shaun, her's how I've been doing it:
Parts from mini-box.com and
logicsupply.com
Intel D945 GCLF board (a problem, not made any
longer)
M200 case (non LCD)
Pico PSU80-WI (WI very important)
1GB ram
I run Limey-Linux off a 256MB CF card.
I replace the blowers on teh case with ones that
have better bearings, the M200 stock fan WILL die after a short
period.
I but NOS or used D945 boards on Ebay.
They just keep chugging along, no disk drive to
wear out, and as long as you don't reboot no added read/write cycles on the CF
card.
For motherborads, I have been eying the Intel DH61DLB3.
But I still have one more D945 on the shelf.
I tried the Pico PSU80. Yes it works, however it
drops out under about 11.8 volts input, AND the 12Volts pass along directly to
the CPU regulator thru the 4 pin connector. Noise on the 12V, or too much 12V
input (voltage swing on input supply above some point) will kill the
motherboard. The -WI power supplies make the 12V as well as the 5V, much tougher
to kill. Next to try is the M3-ATX supply, works on 6-24 volts input, much more
forgiving.
In the future I want to try a Beagle but I have yet
to see a "made for it" case, that would convert me...just when I got a handle on
rolling my own Limey-Linux...

OK, I admit. Have not spent too much time with Mr Google on
this one, but here goes hoping for a short-cut answer................
I
would like to run each of my seven repeater sites (mains/grid powered with 12v
standby bat) each with it's own URI and AllStar node. Some sites will have two
URI's.
Question;
What PC should I use at each site (12v PC would
be nice, and with "auto power on" from dead battery when mains power
returns)
I had a look here http://www.mini-itx.com/ but the amount of
choice is overwhelming. No idea which one is suitable.
Then there is this
thing called a Beagle Board??
The processor must be fast enough to
handle 2x URI's. I tried using a HP netbook and an Asus eeePC but voice
overs were a bit choppy as if the processor was battling.
I do not really
want fans, hard drives or any other antiquated moving devices (when are we
going to see quiet, passive pc's at the workplace?)
I do not need wireless,
just an Ethernet port.
