I was recently able to pick up one of these motherboards on the cheap and now have it set up in a reject NZXT H1 case. (the pcie riser cable bracket where it mounts to the frame shorted and actually caught the pcb part of the cable on fire. It's a documented issue and there are fixes for it I ignored being I've had two other cases and they have been fine, guess I was lucky
). I got my money back for the case and bought a replacement pcie riser cable and I'm back in business.
I've uploaded a dGPU version of open core 7.0 that has the case USBc port enabled, the back USBc port is not as well as one of the USB 3.0 and USB3.2 ports are not to be able to stay under the 15 port limit. You can roll your own by turning on the XhciPortLimit in the config.plist and running Hackintool (don't use or enable USBInjectAll.kext). I'm using the intel wireless and bluetooth card it came with so the Broadcom and Airport kexts are there but turned off in the config.plist. Add your own serial numbers etc.
I can upload an iGPU version if requested, all that needs to be done is change the device ID for the iGPU. Pretty quiet over here lately though...
