If you were to build it yourself, you can find passively cooled N100 Mini ITX motherboards (I own an Asus N100 Prime) which you can fit with a pico ATX PSU or HDPlex PSU. Pair with a SFF case, you could get it around the size of a mac mini without the brick. Maybe something like a skyreach case.

Again, too big for my requirements. What I want is a box I can forget until it breaks or I need something directly from it. RPi5 allows me to do that while handling a ton of workload for me.

Maybe the tasks it does are light from CPU/IO perspective, but the burden I offload to it is tremendous.

The N100 systems I have are desktop systems which spend most of their life powered off or at standby.
