NUC is nice, I measure mine at less than 10 watt for "smash the CPU" tasks, small form factor, good alternative to ridiculously expensive options like car PCs.

NUC is nice, I measure mine at less than 10 watt for "smash the CPU" tasks, small form factor, good alternative to ridiculously expensive options like car PCs. I found it's also voltage tolerant. It's rated at 19v but you can run it at much less (down to 15). EDIT: it does go up to nearly 20 watts, depending, esp if you have the HDMI plugged in. Technically I think you can get more out of a NUC than a mini in terms of raw MIPs. They're PCs, not toys like RPI.
