Samba (and later NFS) on a crappy bulldozer-era AMD laptop combined with a set of USB drives as a ghetto NAS, so I could access data from any system without leaving my desktop on 24/7. It worked, but that thing overheated so easily that I had to undervolt and underclock it to get it to run reliably. I relatively recently switched to a affordable Terramaster NAS, and to using containers, and have been expanding pretty rapidly. The whole Reddit situation got me to start revaluating the services I was using. A kind of software/service spring cleaning if you will.
