Like other mITX boards we've looked at, you can see from the single shot we've got a pretty good idea of everything that's going on.
As we move in closer to the board, you can see we've got only a single expansion slot which is a x16 PCIe slot. Because we've only got a single slot, it runs at the full x16 speed. As for what else is around here, there's not a lot; just above the slot and to the left we can see a header which is for a front panel audio header.
Turning the corner, we've got very little going on with just two DDR3 slots present that support up to 16GB of DDR3 at speeds ranging from 1066MHz DDR to 2133MHz DDR.
