For an actual NAS solution, meaning your primary goal is storage, then Rockstor, OpenMediaVault, and TrueNAS are the big open source ones I know of. I believe they can all do ZFS and RAID these days

If you’re looking for a system to host self hosted apps, that can also do ZFS storage, check out Incus Containers on a playing Ubuntu or Debian install, and use LXConsole for the UI side.

I use Picsur. It’s very similar. I have liked it quite a bit.

RustDesk is great, you can run the server on your own hardware, and set up the clients for unattended access. No need for a VPN, as long as all clients on both ends can find your server.

Sorry for the delayed reply. Haven’t really played Minecraft, so can’t say, but I’ll say I run my own server and the family and I play for while til we get to a point we’ve done what we want, and I then go in and change the world sees and we get a new world and start all over.

I’ll give a vote for Zulip. It’s come a long way over the years, and if you really look at the way they’ve built it, it’s so much better than most options as there is a built in concept of context in threaded conversation.

Veloren has been a blast on my family’s self hosted system.
