Kind of tough to recommend anything since you haven't told us what kind of a CPU is going in it.
Everyone has an opinion on who makes the best motherboard.
I'm going to toss in some info based on my professional experience. I worked in supply chain management for one of the larger PC OEMs, the Top 2 Tier 1 (best ) manufacturers are Asus and Tyan. That is a FACT.
On a personal level, I've had very good luck with Asus and Abit.
MSI, Epox and Abit are Tier 2.
Soyo, Gigabyte and host of others are Tier3 or worse.
The higher the Tier, the greater the probability you're going to have problems... meaning a board from a Tier 1 is better than a board from a Tier 3.
