It in fact has a low-power chip that seems intended for 'embedded', and a nice case. I think the actual usage of the computer is around 6-12W. Four of these show up: cpu0 at mainbus0 apid 0 cpu0: AMD GX-412TC SOC , id 0x730f01 cpu0: package 0, core 0, smt 0 I don't mean to say you shouldn't use aarch64. Just that I found this to be low power and very reliable, and because it's amd64, to have almost no "this program doesn't work on CPU X" issues. And, I didn't find something with multiple interfaces and 4GB of RAM that came in a box with good mechanical/thermal design, a few years ago.
