When this NUC is under significant load, the fan sound is annoyingly loud.But otherwise this is the fastest NUC yet.I also received this NUC with two broken screw holders (I guess that's because by now they are mostly selling used devices), so I returned it and ordered a minitower instead (less noisy!).The good thing about this NUC Skull is that it works with Windows Server 2016 (most other NUCs do not support Windows Server).
