Wow, I love that case
As for the motherboard, don't worry, it'll fit, as its ATX, which means its a standard sized board, and the case your choosing is also standard ATX sized
To trust my judgement more, this is whats on the detailed specifications of the case, that it supports:
Main Board: ATX, MICRO ATX
Main Board Size: Fits up to 11" x 12"
So, the case is big and wil have ample room to spare for the motherboard.
