Installed Ubuntu server 22.04LTS very easily.  Only challenge was I never figured out the magic key to get into the bios during start-up, so I had to set up windows just to access the bios, to get the system to boot first off the usb stick holding the installation system.Currently using the system for its intended purpose, as a headless SMB server for our Sonos system; all our music (we don't have a huge collection) in lossless format can fit on the supplied internal storage along with the OS.I had tested the system with the ubuntu desktop live-usb before installing ubuntu server, and can report that HDMI video worked perfectly (didn't test audio), as well as wifi, bluetooth and all the USB ports.
