The NUC is running solid for about a year now. Its a powerful yet energy efficient machine. The only reason I didn't gave this a 5 star was due that annoying fan issue where the BIOS will (i believe incorrectly) report high temperature and the fan RPM will go higher resulting into a noisy machine. While this issue doesn't happen often (has occurred about 3-4 times in past year), its an annoying issue nevertheless and I have to reboot the NUC to bring things back in order. I have updated BIOS, tried various settings all in vain. Beside this issue, the NUC is a great little machine.
