I'm in a weird transition phase right now because I deprecated my big boi server when I moved into my new studio. I have a dumb Lenovo NAS with a mini pc that acts as the "brains" of the setup. (I actually need to do a reinstall of my OS because I've been having issues with my Debian setup.) This serves my Jellyfin instance and handles the brunt of my data hoarding activities. I also run a Nextcloud instance, but that's currently running on my cloud seed box while I wait to build a new home server.

My biggest goal for this year is to get my new server built. It's going to be the do-everything server for me. On top of NAS functionality, I also want it to serve a KobaldCPP instance. The biggest challenge there is going to be hardware selection, particularly trying to find a graphics card that has ludicrous amounts of VRAM without bankrupting myself in the process. I was considering doing some home networking stuff, but I really don't need anything more than my ISP's router for what I'm doing right now, and I'm pretty space-constrained since I live in a studio. We'll see, though!

A home media server is a good start (jellyfin, for instance.) I also think nextcloud is a swiss army knife, and spinning up the nextcloud AIO would get you're feet wet with relatively little effort to how much stuff nextcloud can do (all the differents apps you can install from the web interface. I use news, cookbook, bookmarks, frequently.)
