Depends on what you’re doing.
If you want a low-power setup, get a shell with a backplane for 4 drives and an n100 board.
If you want to host games, get an AMD APU on a mini-itx and do the same.
Maybe a 20-40W difference, but the AMD is going to outperform the n100 like a hot knife through butter.
Yeah, it’s super attractive until you realize the current conditions we can technologically handle that. It’s dangerous slave labor.
Good luck selling that to the era of kids working a MacDonald’s.
