A mini PCs sips power when they’re mostly idle, at about 10/15w then it creeps upwards if you push it. It also only needs the iGPU anyway even if you wanna do trancoding on Plex. It will most likely be way more efficient that a desktop with a GPU on it
I think the best choice is getting one of those so all your services are working all the time. A RPI will work albeit you gotta be aware of its limitations.
If you’re satisfied with Jellyfin, you should stick to that cause Plex ain’t bringing much to the table in all honesty. I still use Plex cause it works better most of the time really.
If you want a FOSS alternative to fetchnotifs, you can try changedetection.io :)
It still works fine so I’m assuming no one is paying for it, including myself :)
Libreddit is great, been using it way before the Reddit drama (libreddit.caldeirag.xyz), there is also Teddit which is similar, they both support the cookie subscription thing.
Libreddit uses anonymous endpoints that still work for now, I use Libreddit daily on my instance.
I have it running for a couple of months now, doing just fine. Had to change my compose file a while back due to some change but rock solid so far.
I do run Syncthing too in any case
