I bought 3 of these. One kept shutting down all the time no matter what OS I put on it (the windows it came with, win2016 server, or Ubuntu). It was after the return window so they wanted a ridiculous restocking fee when it was a definite hardware problem. It started not even booting. Just...try another brand of minipc. The other two seem to be working fine but I am just waiting for the other shoe to drop on them.
