TL;DR: have a server and want an OS for it. Currently using CasaOS. Any and all recommendations GREATLY appreciated.

I have a homeserver that I have 36TB of storage for and I want a nice simple OS to use.

I’m currently using CasaOS but I keep hearing bad things about it such as very poor security.

I’m thinking of moving over to Cosmos OS which is similar but lacks a file manager.

I really just want to be able to use Jellyfin/cloudflare/other fun apps. I also don’t know annnything about linux so I love these web GUIs.

Im open to some kind of linux desktop but preferrably something with very minimal experience needed.

Thanks!
