New to the forum (and to Libreelec). I've been running Windows on a NUC5PGYH but recently decided to switch to Libreelec and use it as a home theater PC. (A Better Fit for the NUC5PGYH – Techster's Blog)
I regularly post about Intel NUCs, and do a lot with them as HTPCs. I just learned about Libreelec and so far am very please with it.
Happy to answer any NUC-related questions.
