That’s probably what I’ll do next time but there’s something nice about having it be a single thing on the desk, and the last two times I bought one it was cheaper than buying separate parts (trading longevity).
Or if you buy a nicer mini then you can get a nicer display later on. The iMac is still limited the base M3 CPU, while the current mini is available in either M2 or M2 pro. Hopefully they update the Mini with M3 pro because that's what I've been waiting for.
