I had an HP Microserver N36L since 2011. Despite its low power it served me well as test machine, then converted to a NAS running Debian.
When the main disk failed, a >10yo 250GB Seagate Barracuda, it seemed a good time to give a new life to the old but good server.
After evaluating some options, the best use for my need was a NAS with options to run Plex and some VMs or containers.
