> or similar? If so, I see BQL support in that code,

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

> I see a Gen 10 available here for slightly more with the same BCM5720 NIC, and a AMD Opteron X3216 instead, plus 8 gigs of RAM, which I don’t need really, but I can search more for similar hardware: https://www.alza.cz/hpe-proliant-microserver-gen10-d5127723.htm?o=1

	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.
