So the desk in the above video is the kind of setup I envision a lot of people might use for the M4 Mac Mini. At around 5:07, you can see the Mac Mini snugly stored in a cubby hole on the desk. The location of the power button means that if you ever need to hit that button, even if it's once a year, you need to pull the Mac Mini all the way out.
As I said before, not a deal breaker, but fairly annoying.
