Currently using Unraid. I like the docker management, plugin support, and the flexibility with adding storage. But I do already have a lifetime license that I got for cheap a few years back. They’ve raised the price significantly since then

If I had to choose today, I’d go with TrueNAS Scale

I’ve tried a couple different KDE distros and settled on Fedora 40 KDE spin. It seems to be the most complete KDE experience without all of the Canonical/snap bloat. It works great on my Thinkpad. Also runs decent on my gaming desktop using the latest Nvidia beta driver - I used to get stutters and artifacts in games/steam/plex and now with the beta driver those apps run fine
