Hi Alan,

we have some Opteron cluster nodes and some Opteron workstations based 
on the Arima HDAMA MB (Rioworks http://www.rioworks.com/HDAMA.htm).
We are quite happy with those systems, because there are running without 
any failure since installation (one year ago).
And as far as I know, there are some 1U barebones with this type of 
board, too. If you looking for a remote managment system on your 
motherboards, there is the possibility to attach an IPMI-Board called 
ARMC to the HDAMA. This would give you the same mamagement features like 
the Newisys boards, but for additional costs (~300 US$ ??) and size.

Thomas
