I picked up a NUC8i5BEH (H being the tall one so an SSD or 9mm tall 2.5” drive can sit inside) and installed Roon ROCK on it. It’s under the tv as that’s the only screen I own with hdmi connectivity. Works perfectly, and is nice and responsive. Quiet too, once I got past the initial analysis of files, and even during analysis you’d have had to listen carefully to hear it.
Very pleased with it. Although I’m not doing so, NUCs run Windows perfectly well, and they’re small enough to fit to the rear of the monitor. Do that and add a wireless mouse and wireless keyboard and you have a very tidy setup.
