hardware recommended for 1U server

[William Wager]

Hello list,

I'm was wondering if anyone could recommend me a updated Athlon XP/Pentium 4
motherboard that has no problems with running FreeBSD 5.2.1 and fits nicely
into a 1U server case. As far as I know the only physical problem with
motherboards and 1U cases is onboard sound with sound ports sitting
vertical.

This board will also be bought from the UK so a board that can be sourced
from a UK supplier is a big plus :)

Regards,

Will
