If you are going to have the EVO's fan blowing towards the back of the case, I would avoid memory sticks with tall heat syncs. The EVO sits quite close to the board.
My EVO needed its fan raised a bit to clear RAM in the first slot and I didn't have that tall of heat sync on my sticks. If you were to orient your EVO so its fan blows up towards the top of the case, it probably will be OK. But you'd want a case with a vented top to do that I would think.
