Purchased the NUC 7i3BNH in Oct 2017 and it stopped working Sept 2018. While the unit was operating it simply died. No amber stand-by light on the power button, no sign of life. I tried a power adapter from another NUC (5th gen) that I know is good and no difference. I have opened a service request with Intel and we'll see what happens. Completed all the troubleshooting steps they requested but there is simply no indication of power getting to the unit, but it must be internal. Never had any problems with heat.While it did work it was a fine computer. Did everything I needed it too. The 5th gen (5i3bnh I believe) i bought back in 2015 is still working fine.Edit (9/23/18) Intel is replacing the unit, should arrive tomorrow. Excellent customer support if you ever do have problems.
