I use Casa"OS". It’s fine, but nothing groundbreaking. Cockpit for example can do pretty much the same, and for Docker containers, I nowadays mostly use docker compose.
But hey, it helped me a quite a bit in the beginning, and it’s cool. Pretty basic, but enough for most people, mainly beginners.
I chose to continue with my current setup until I get the time and motivation to upgrade.
I will build a new server from scratch. For that, I bought an used mainboard for a few bucks, which has 6 SATA slots.
