Mini-ITX board I think. 2 ram slots, 1 PCIe slot (I think? hard to tell but if the board extended down past the first PCIe slot you should be able to see at least a bit of it out from under the GPU). Looks too small to be micro-ATX.

Yep. This is the real travesty here. If you're going to use a huge case like that, why on earth would you put a dinky little motherboard in it?
