I added two Instinct MI50s from basement, and unplugged my (only) 32GB Instinct MI50 GPU from x16 PCIE slot inside PC and connected outside as well.
This is system working.
All 4 long and 4 short GPU power cables of Zumax 1850W PSU are now in use.
4 long, 1 short and 2 cables with 2× SATA and 2× Molex each leave PC through side hole in PC case.
SATA splitter cable leaves PC back together with remaining 3× GPU power cables.
The 4 Molex connectors are used to power the 8 BBQ fans.
The Riser modules are powered with 8 SATA connectors.
I had to replace the 4× Riser card with a 6× Riser card, one x1 adapter plugs into x16 slot now:
After some recabling, now the visible GPU UUID order corresponds to OS view:
Leftmost characters are hidden by 3Dprinted holder in photo, rightmost characters can be compared:

Total 3Dprint time for all stckable MI50 holder parts was 48 hours.
