I'm in the means of buying a mini pc for selfhosting stuff. My main reasons are sailing the high seas for movies and series and hosting my families photos, videos to escape gdrive. I'm thinking about some kind of DMS / digitalizing paperwork and mail in the future.

I casually look into all kinds of software that could do the task and now I'm a bit overwhelmed. Is owncloud or an alternative enough, or do I need something more elaborated like TrueNAS? But all the NAS Foss stuff seems to run on their own OS. Can my Pirate Ship run on that? I feel like the diversity of solutions is making this very opaque for me.
