I have an SC420 in one office that works quite well.  I think the
confusion comes because you can't use the bios to change what
interrupts are used by the various integrated components on the
server.  The result is that if you use the first PCI slot, the Digium
card WILL share an interrupt with the integrated network interface,
and you're liable to get missed interrupts and choppy sound under
heavy network traffic.  You can easily get around this by using a
different PCI slot.  I have perfect sound with the SC420 (although
I've never heavily taxed this machine).
