I recently bought this mini PC, the goal was to install FreeBSD and use it as daily-driver, unfortunately I couldn't meet some specific criteria thus I had to move on Linux... 
Anyway I used FreeBSD for one week and my evaluation is surely positive, here a brief recap:
If compared with my previous setup, which was a SBC LibreComputer ROC-3328-CC, the difference is abysmal. Same size, better performance, it is a real computer, I use (and used) headless with TigerVNC and you get GPU acceleration and X working flawless.
If you're looking for a mini-pc to run FreeBSD, this works just fine.
Thanks...
