Sure,

	I believe sometime in the past I confirmed BQL working, but my memory is hazy and this might have been a different machine...

	Then gen10 microserver while newer comes with a soldered in pre-ZEN amd cpu and seems less extensible then the gen8, but then the gen10 probly is also a decent machine.
