Server for a boat (lemmy.world)

Good day, friends. Since catching the self-hosting bug, I've set up a couple of Proxmox home servers with a bunch of services I enjoy.

Now I'd like to set up a server and local network on my sailboat so I can self-host servarr, pihole, and other services while traveling. The tricky part is that everything on the boat is 12V and I would rather not use an inverter, if possible. Also, it needs to be ultra-low power so I can leave it on at all times and not to deplete my batteries too much.

Criteria:

ultra-low power
Small form factor
runs on 12V
10 TB of storage plus ability to make full local backup
Capable of hosting servarr, audiobookshelf, freshrss, etc. via docker
HDMI output
Full local mirror/backup of the entire file system, including the media library.
We will have two laptops and two Android phones to access the server, so the server doesn't need to run a desktop environment.

I'll have a mobile wifi router and a cellular signal booster (or maybe Starlink eventually) for internet access. Since internet bandwidth will be limited and expensive while traveling, I don't want to have to re-download a massive media llibrary if the storage media fail. Thus, I want the media library to be mirrored or fully backed up or synced locally.

What hardware and Linux distro would you use in this situation?

Your best bet might be to use a laptop as the basis. They are already designed with power efficiency in mind, and you won't need an external screen and keyboard for local problem solving.

I would also consider having a raspberry pi 3 or similar as a companion. Services that must be up all the time run on the pi (e.g. network admin). The main computer only gets kicked out of sleep mode when required. The pi 3 needs less power than the newer pis, while still having enough computing power to not lag unless pushed hard.

I definitely agree with SSDs. HDDs don't do well when rotated when running. Boats are less than a stable platform.

HDDs don't do well when rotated

The original iPod had an HDD in it. You can rotate HDDs. Sharp impacts may be risky though, especially for a non-laptop drive.

HDDs can be made tolerant to it. Constant rotation still puts significant extra strain on the bearings, when spinning however. The drive will likely fail faster than an SSD.
