Hi all,
Just for your interest, there's a new POWER9-based mainboard from Raptor called "Blackbird", with a much lower price point than the TalosII which seems to be more desktop class than server oriented:

There's also a 4-core and an 8-core bundle: https://secure.raptorcs.com/content/BK1B01/purchase.html https://secure.raptorcs.com/content/BK1B02/purchase.html
This could make for a nice coreboot target, since so much documentation is open, and since it shares the open source spirit with coreboot...
Documentation is available on the wiki: https://wiki.raptorcs.com/wiki/Main_Page
Cheers, Merlin
PS: I know this isn't fully on-topic, so I hope nobody minds me sharing it here.
PPS: There's a special pricing going on until monday midnight!
