While very responsive to including the features that the overclocking crowd desires, I can't recommend you pass over the proven solutions like the Albatron, Abit, or Asus boards. My experience has been that Iwill is not the equal of these products. Not that they can't work well, but the overall level of refinement falls well short of the best available.
There is a 845pe roundup on THG that includes the Iwill. You might take a look at it. While far from the definitive word, I don't know where else you can get usefull information on this board.
