Little bit of a bump and update:
I've got most of the parts together for this build now, but I'm still having a few issues (mostly finding a case that will fit the giant motherboard, but I think I have that covered finally).
The P3 500s I have both came with these enormous passive heatsinks that are obviously not compatible with the plastic retention arms on the motherboard. Is there a specific active cooler I need to get?
I had read something about SECC vs SECC II and I'm wondering if this board only supports the former. Any suggestions are greatly appreciated!
