Well, so much for going with that big heat sink cooler. It just isn't going to fit. It bumps into the voltage regulators on one side of the board, and the USB 3.0 front panel cable on the other.

So for now I'll be using the stock CPU cooler, and taking the PWM fan from that heat sink and mounting it on the top of the case. So it'll blow down on the CPU's fan, that's blowing on the heat sink.
