I use both. The NUC states 19 volt DC but runs quite happily on 12 volts. The Minix has a better WiFi range due to its external antenna. The NUC is an i3 with 4gb ram and a 250 gb SSD. The minix is 8gb ram and a 64gb SSD. Both run windows 10 pro and I use Windows remote desktop to connect and control.
