Just built what you are going to do-
love the board-some quirks-got to abit-usa and try max2 forums for how to use the cd that comes with the board-or your usb ports will be dead or freaky-just follow the threads and you will be ready to go.
My first build-had a 33 year ibm vet for backup at all times-he said the board had the most features he had ever seen-raid is teriffic-some issues with the seriat ata-but if I had to do it over again, I would-except I might pop the extra $70+ and go for the 2.66 chip-it looks like it does about 50% better in some of the sandra benchmarking.
I bought an antec 1080 430 wt case for $105 as well-picked everything up same day in Silicon Valley-@$475 incl tax for case/mobo/processor.
Good luck-I thought about the asus as well but the highpoint raid setup seemed better received than the promise raid controller-that is the one on the asus if I remember correctly.
Bios on this one is virtually idiot proof as well-so far
