This is a long shot, but: does anyone have access to a Supermicro H11DST-B *version 2.x* motherboard?

We (@hswaw) suspect that the only important difference with 1.x is a larger NOR flash for the firmware. If so, a little hot air action would allow an upgrade to Zen 2 CPUs, and get big perf/power-efficiency gains on a budget.

Boosts much appreciated!
