This is a fast, quiet, affordable, low profile PC for hosting a webserver, file server, shell server, etc. Installing Ubuntu Linux was a snap (booted off of a USB). Contrary to one of the answers on the questions page, it does not come with Bluetooth so I got
  
Plugable USB Bluetooth 4.0 Low Energy Micro Adapter (Windows 10, 8.1, 8, 7, Raspberry Pi, Linux Compatible; Classic Bluetooth, and Stereo Headset Compatible)







  
  
    which was recognized immediately by Ubuntu.I initially had the device set upright, but it has lots of LED lights flashing on the bottom of the PC which was annoying at nights so I set it flat, only to realize this fanless device gets warm when set flat. So it's back to being upright, but it's against a cardbard box to block out the lights yet keeping the airflow.
