Doesn’t need to be dev stuff, sure many are into that but a lot of folks are more tech curious. I’m good with music software but I can’t code at all, luckily people have made tools that make it a lot easier. My home set up uses Yunohost that essentially gives you big friendly buttons for setting up and running things, most of the command line stuff is abstracted away. My music, podcast, shared files etc. all run on a little computer I bought second hand on eBay for £200.
