I finally got around to ordering the parts (I had to try SIX different vendors in Hong Kong before I was able to find a place that actually had this motherboard in stock, five of them cancelled my order). I'm currently installing Windows and plan to start on MacOS tomorrow. I have a very similar but not identical configuration to yours. For example, the CPU is a Core i7 10700F, and the GPU is an RX 6600 XT. (Same motherboard!) How much work is it going to be for me to modify your EFI to work with this GPU and CPU? Do you have any advice, other than trying to follow Dortania's guide?
BTW, I got the Noctua NH-U12S fan and am very pleased with how silent it is, at least when the CPU cores are not maxed out.
