I've recently put a machine together around the M2NPV-VM.  Currently it is 
doing BE/FE but will eventually be a diskless FE.  I've only been using for 
SD but it works fine.

A couple of things worth mentioning:

There is no onboard S/PDIF, you need to purchase a little expansion board.

The heatsink on the onboard graphics is small.
Running fancontrol to quiet the cpu fan results in a _very_ hot chip and 
surrounding board.  No stability problems but I've only run it for maybe 3 
hours at a time.  It can't be good to be that hot.  Airflow when the cpu fan 
is fullspeed is enough to keep it cool though.  Until I get a quieter HSF 
I've got a cardboard duct going to a case fan.  I moonlight as a breakfast 
cereal duct designer for NASA so this might not be an appropriate solution 
for those without access to the requisite precision machine-shop.
