Ah yes thanks for checking! Alex already spent time figuring them out. It turns out they're incomplete (or at least the ones he looked at where incomplete). They run linux. A pretty nice chipset apparently, but they only have a single-antenna 2.4 GHz wifi interface for management. There are supposed to be three mPCI-E slots but not only are the wifi adapters missing, the actual mounting adapters haven't been soldered on so you can't install any mPCI-E cards. They could be used as wired routers but it doesn't seem worth the effort unless you have a need for a lot of them.
