I gave my 580 to a WINDOWS BOX. Threw in a couple of M2 drives, a big spinner, I-7 six core, 32 gb. Total cost not counting the 580.. under $300. It was worth it to get over the Mac - Bootcamp headaches. I did drop a pretty penny on the Vega 56, it is smooth as butter, I can access recovery, etc. So Now, the Mini is 100% macOS.. The windows box is next to it. I use a Synology NAS to sync all the important files. It is nice to be able to do a Windows update, and not brick Bootcamp.
It's a pleasure to be on a working Mac again. I had about 50 books to transfer to my iPad Pro. Now just the nagging bugs in Catalina.
Take care all, we have the best Life Hobby of all.
