I bought this for a friend to be the backbone of a 4 camera security system. The only thing running on this box is Windows and Blue Iris with 4 POE cameras attached. Even without Blue Iris running this thing will freeze whenever it wants to. It is the most frustrating thing to spend this kind of money on something that constantly freezes. The part that is even more frustrating is that the security system is located at their lake place which is almost an hour away. So you get the thing running and before you can get home it is no longer online because it has frozen. So yet another almost hour trip to get it back up and running only to drive an hour back to find that is is not online again.The distance makes troubleshooting virtually impossible. I have updated BIOS, drivers, etc. I have tried to disable different things all with the same result. Sometimes it will work fine for hours and sometimes it will freeze before it can even fully boot up. I am going to have to cough up the money to buy them a new machine so that I can personally own this little block of frozen junk. I don't have a use for it at my place, but I cannot leave their lake place unprotected.I would not recommend this to anyone and if you are in the market for a Nuc, I would strongly suggest you look closely at reviews and work it hard in the beginning and if it freezes once, do not think you can fix it. Return it before you cannot return it anymore.
