From the size of that sledgehammer mobo (It'll be a cold day in hell before I say "Opteron") I'd going to make a prediction:
SLEDGEHAMMER MOBOS WILL HAVE SUCK-ASS LAYOUTS
Probably 2 PCI slots, a short AGP slot (not AGP pro), RAM slots placed randomly around the board, without rackmount-friendly slants, capacitors packed right up next to the slots, making installation of a decent heatsink impossible, and forget about integrated ethernet and video.
I say this because production mobos will have to be MUCH smaller than that card table of a PCB to fit into standard cases.
But if it's fast and stable, who cares?
