This is the first ifixit repair guide I’ve ever followed. The 3 steps I was most worried about...Step 6: antenna cable connector removal. Step 10: fan cable removal. Step 13: LED indicator light cable removal...weren't an issue at all. In fact the only step I had an issue with was Step 15 (pushing the logic board free) and that's because I wasn't pushing hard enough. Overall, a little scary to crack open something brand new that's $1k but I was able to pull it off without issue. (thankfully). Now this Mac mini is running with 32GB + 3 monitors and should last me the next 4 years till Apple updates it again.
