All the NUCs and other mini PCs I see run mobile processors.
It’s a shame because a simple downdraft air cooler with a 120mm fan can handle a pretty high power load and could definitely fit in a tiny space.

I have one as well. Its really nice, but the biggest drawback imho is it only support 1x2.5 inch drive
