Thanks for the feedback!

1. I may not have labeled that accurately, I just plan to use Tailscale to access these services from specific authorized devices.
2. I meant “before I do something that is a pain to correct”. Like starting with the wrong OS or file system format.
3. My plan is to build a media server which will include 4k media, so I think my storage may need to grow over time… maybe TrueNAS is something I can add later if needed?
4. I guess the reason I was thinking of 2 separate machines is that I’ve heard using an OPi as a media server or NextCloud server will go really slow and potentially cause other issues. Plus I already have an old computer doing nothing right now, just needs new SSDs.
