Are these demo boards for the smaller BTX form factors?
They sure don't seem to allow for much in the way of expansion. Hopefully the production boards will have a bit more in the way of PCI-* slots and drive ports.
The picture angle is a little steep on the larger board, so I'm not sure if a long video card could get in the way of the one drive port, nor if a two-slot card would either get obstructed by the power cable or cover over half or of the PCI-Express slots.
Maybe it's just that the boards are not finalized, but it looks like there is a bit more wasted space and oddball placement on the boards thanks to everything being shifted around to comphensate for the CPU's thermal shortcomings.
