I am also happy to say that I've completed this build successfully! Thank you so much for you guide

Running High Sierra 10.13.3 on iMac18,3
BIOS version F7h
The only big difference is using a NVIDIA 1080 Ti instead of an AMD GPU,
the hardware is as follows:
- Intel Core i7-8700K CPU
- Gigabyte Z370 Aorus Ultra Gaming Motherboard
- Corsair Vengeance LPX CMK32GX4M2B3000C15 32GB RAM
- Gigabyte AORUS GeForce GTX 1080 Ti 11G GPU
- Gigabyte GC-ALPINE RIDGE Thunderbolt 3
- Corsair RM650x Power Supply
- Samsung 960 Pro 512GB NVMe SSD (for MacOS)
- Samsung 850 EVO 500GB (For Windows)
- Scythe Mugen 5 Rev. B CPU Cooler
- Fractal Design Define C Case
Notes during install: I did not select any Graphics Configurations in MultiBeast for the NIVIDIA GPU. On first boot into the system the GPU isn't recognised but using
Benjamin Dobell's nvidia-update (
topic) getting the right driver for the system is as easy as every.
As I just finished the build I haven't been able to really test the system for longer periods, but everything seems smooth. Thunderbolt 3 works great on MacOS, tested with a Caldigit TS3 Plus. I dual boot Windows (for gaming) & MacOS (for video editing/color grading) through Clover. To get rid of useless boot entries I disabled them in Clover Configurator (GUI section). What
does happed every now and then it that MacOS boots into the
Prohibitory symbol. I'm not sure why this happens, but a reboot always helps.
To disable the stupid LEDs on the Motherboard an GPU I've installed the AORUS Graphics Engine (
download here) for Windows. I don't have a window in my case an find light coming out of my PC not really appealing
