What's your idea of very little power, though?

I know for many who run SBCs (RK3588, Pi, etc.), very little is 1-2W idle, which is almost nothing (and doesn't even need a heatsink if you can stand some throttling from time to time).

Most of the Intel Mini PCs (which are about the same price, with a little more performance) idle at 4-6W, or more.
