While not officially on Intel's list, this model does NOT support Legacy Boot.  Only signed OS's will be allowed to boot on these computers... meaning most Linux and Pre-Windows 10 environments will not work on these computers.Also, I bought two and while one works reliably, the other will not turn on without opening it up and fussing with the works... sometimes I just need to touch the main harness, other times I need to open the "CPU box" and reinstall the RAM, or perhaps just push and pull and poke at things...  I did set UEFI to boot on power restore and this seems to help, but as far as using the power switch to turn it on... good luck with that!
