It was clean and ready to go out of the box with windows10.  After seeing what it was out of the box I installed ProxMox for some home lab stuff. IT was then I noticed that the SSD has no mounting screws so the SSD is free in the form factor to rattle around.  Ill have to buy the HP proprietary mounting screwsCurrently testing the Off Brand (MUX) SSD that came with it, lets see how long it lastsUPDATE: After a month the power supply failed. had to return as amazon and vendor wouldn't do a patrial refund or send a new power supply
