Dont' know about the Shuttle board... However, I'd say to go with the top condenders. If you got some money and want to overclock and know quite a bit... go with the Asus A7V or the Abit KT7. If you want to overclock but on a budget, go with the MSI K7T Turbo or the ExpoX 8KTA3 if you're not too into overclocking. Iwill kk266 if also good but a little on the high price range. Personally, I'd get the K7T Turbo or the Iwill KK226 if I have a little more money.
o yeah... 300W!!!
