I've got the opportunity to test recently the Intel Skull NUC 6I7KYK, and these are the overall comments to the product and why I returned it back:- The performance is very good.- The Thunderbolt por 3 works perfectly, even supports the DisplayPort Alternate Support for Asus MB169C+.- It does not have room to allocate a 2.5" drive (the newer NUC7i7BNH will have it).- The worst part, and why I returned it back, is because both the power supply and the barebone itself emit high magnetic and electric fields, which I found very uncomfortable and cause head and chest pain depending on the position you put the barebone. The products should be shielded properly so no field get out (except the electromagnetic radiation for the WiFi and Bluetooth technologies, that you can disable on purpose).- The case in totally of plastic except the bottom, which is ferromagnetic metal. It creates a false sensation of a premium product.- The barebone is not earthed (the ground pin that goes to the barebone does not connect to the earth pin of the mains wall plug), so you get floating voltages. You have to use a USB cable to connect its negative to the earthing pins on the wall socket.
