I took this cube, which was smaller than I had imagined from the packaging and (as I had never before run on a server Windows) directly installed Ubuntu Server. After a bit of Googling I found the easiest way that I want to make available also here: Pull out the bottom (operating system disk) and connect as a single disk on a PC. From there, install the system off and before switching off the automatic restart at the end of installation the computer and the drive back into the Easystore. Then these starting and after less than one minute of Easystore is ready for use. The small cube is absolutely silent (I have not believed the reviews), fast and hardly needs electricity. So, the description applies to the applications that I need to complete. Also to stream HD movies no problem. On the whole, the Perfect Home Server. I can only recommend.
