The GA-MA74GM-S2 looks like a nice board. It's more than half the price of the other 740G's I've been eyeing. The only problem is it's not mini-ITX which is a must for the Chenbro ES34069 I've fallen in love with. I agree that undervolting/underclocking is the way to go. Difficult, if not impossible, to find in these mini-ITX platforms though.
