asterisk users - May 2005 - Xeon server board for TE405P

I would appreciate if people that have experience with stable Asterisk 
and TE405P cards installations on Xeon servers can share what kind of 
motherboards and chipset are using. I'm trying to configure a new 
Asterisk server with one TE405P on an Intel board with Xeon 3.0Ghz but 
not all Intel boards and chipsets works fine with these Digium boards.

Thanks for your help !
