These things will definitely end up in racks in a few places.
Already are!
We just put eight M1 Mac Minis in our racks… and we’re looking at purchasing several of these to go with them. They are joining racks of “trash can” mac pros and some of the current gen rack mountable Mac Pros (which are insane… they are huge and heavy and their compute density is HORRIBLE).
The density of the Minis is pretty damn good!
These are all used for testing (continuous integration) of our scientific applications. In our test farm we have a few hundred cores of Apple gear to go along with ~3000 cores in Linux boxes. This all sits next to our 100,000 core supercomputer.
Yes. I enjoy my job ?.
