Gentlemen,
I sent an email to Roman about this. Here is his reply:
Dear Hans.
It's impossible to just replace a motherboard, there are several complications, you'll need:
1. A new adapter for USB connectors (adapters from a motherboard to USB connectors, they are different in different batches),
2. A new adapter for LVDS display (different in different batches),
3. A new adapter for the wiring cable (different in different batches),
4. A new rear panel with new motherboard connectors outlay.
Internal power supply is enough for i9, we've installed i9-9900 for some custom MB1 Prime units.

So the rear panel is no problem for me, I’ll just cut out a hole the size of the innermost panels hole. And I’ve written to him if there are commercially available adapter’s for the cables he mention.
