The guts of the M1 mini are significantly smaller than the case. There was a video where someone made a smaller case recently that shows just how much you can shrink it.

I mean, it's basically a phone minus some of the cell chips and the display.

Maybe they can do a handheld Mac Micro or Mac Nano.

Thank you! Will give it a try then!

I was surprised Apple didn't sell a 20th Anniversary Cube. It would have closed the loop on what the Cube started. Maybe they'll do it on the 25th anniversary, in a couple years?
