I’ve recently switched HA supervised (running a single rack server) to HA Green, I’m very pleasantly surprised by the performance of green and the fact that I do not need to maintain the underlying OS myself!!
HA Green hardware is quite modular but I wish if there slots provided on one of the sides to mount in vertically say behind a desk or on a wall. Just thinking like how most power extension strips have two slots that cane be mounted two screws or something equivalent but more reliable than a double sided tape.
