Well if you're looking for cheap and are not opposed to a P4 for a processor the PC Chips M921L for $26
might be worth looking at. PC133, sound, LAN, AGP, microATX.
The real deal, for a couple bucks more than the MSI, is the Biostar M7VIG PRO
. It is a more feature rich choice, AMD XP solution, PC133 or
DDR, 6 channel sound, LAN, AGP, USB 2.0 all in a microATX form factor.
Personally I'd go for the Biostar M7NCG (Nforce2) for $108.
