Needed: Motherboard Recomendations

I am looking for an integrated MicroATX (or FlexATX) Socket 478 
motherboard.  It needs to have onboard video, sound and LAN.  I plan 
on puting a 2.0GHz Celeron on it.  I want to experiment with lowering 
the core voltage to ~1.1V from 2.525V in order to lower the thermal 
output (there have been reports of this working).  The goal is to build 
myself a fanless PC (still working on the power supply issues).  There 
will be no hard drive just a decent sized RAM drive and NFS mounted 
partions.

Thanks
