With Power8 aging and Power9 shipping... Consider picking up a
couple of these to support the development of getting FreeBSD going
on the bare iron without hypervisor. FreeBSD being a member already,
good support for this effort should be available from the OpenPOWER
Foundation / IBM. They seem to want to make Power9 and beyond happen
in a big way. Linux also has support for Power9.
A barebones selfbuilt machine for the dev cluster would cost about
$3200-$3500, and/or donation could be solicited from OpenPOWER
