Self-hosted services, in a box?

First off: apologies if you're looking for an answer and not a question! I don't know if self-hosting-in-a-box exists. I want you to email me and tell me if it does.

Motivation

Currently, my photos and documents are sent to an all-powerful tech company's servers where they are, of course, carefully scanned for personal details that can be sold to businesses (and governments), so they can influence (and coerce) me.

Here are a few more appealing alternatives:

  1. Encrypt everything myself prior to uploading to Big Tech
  2. Switch to services hosted by businesses that actually respect my privacy (Proton?)
  3. Self-host my own services, bypassing Big Tech entirely

The first option adds friction and removes features while still relying on Big Tech, so it's only a moderate improvement.

The second option is probably actually the correct answer because others in my family could reasonably hope to understand it.

But the third option sounds the most fun, and is also probably the cheapest, and it's difficult for me to pass up both of the qualities.

My self-hosting dream...

Ideally, I would have a server sitting in my basement that is:

That's a daunting list, thus reinforcing my hunch that paying for services is probably the best option. Yet, I persist.

...in a box

Wouldn't it be great if there was an ISO for a server operating system, with an installer (or GUI) that set all this stuff up?

The closest things I've found to this are:

HomelabOS looks like it requires a client computer with Docker and a server running Debian or Ubuntu. Sovereign looks like it is more opinionated (e.g. requiring a VPS and tarsnap).

If there are other options in this space, please email me to let me know!

DIY

If I was going to set this up myself, I would try shoving everything into a NixOS configuration. Namely:

Bonus points for throwing a basic, web-based GUI on top of the NixOS configuration for toggling services on and off.

Surely someone has done this before! I really don't want to have to do this myself. Well, actually I kind of do, but I should probably spend my time elsewhere. And, as stated previously, I should really just pay an ethical company to do all the hard work for me, especially if I ever end up incapacitated.

NixOS

One last note: why am I looking at NixOS? A few reasons:

Wrapping up

Will there be a "part 2" to this? Who knows! There probably isn't even an audience for this sort of thing, so I really should be spending my time on something else. But it's such an alluring project that I feel compelled to at least give it a try.
