Depending on the model and brand, there's probably a YouTube video showing how to disassemble it. This can help you find the keyboard connector and how to disconnect it.
So the only difference is one is a phone, and the other a gaming device? Because Nintendo js a gatekeeper in exactly the same way Apple is. Nintendo controls the entire operating system and which apps you're allowed to install on the Switch. You're going to have expand on how Apple has economic power over other companies and people for me.
- What’s a good NAS OS to install?
TrueNAS Scale is the go to. Unraid is another popular option.
- Any fun things I can do besides plex transcoding with a 1080 GPU?
Local LLM. Look up Ollama.
- Would it make sense to run a Pixelfed/Mastodon server off this guy?
You could. That could potentially use a lot of space or be very annoying you having to manage and moderate the instances.
- Can I run a RAID on it without buying a separate HDD bay?
What do you mean? Are you talking about a hardware RAID card, or can you physically stuff more than one disk drive into the chassis? For the first, it'll depend on whether it has any open PCI Express slots. For the second, what do you see when you open it up? Are there 3.5" or 5.25" bays open?
Other than a Plex port forward, I have zero experience putting services out on the public web (but would like to learn!).
Wanting to learn is an admirable goal. I've not done it myself, but the Linux Upskill Challenge might be a good place to start. Either that, or figure out something you might want to host yourself, then come back and ask for input when you run into trouble or have a question.
It's most useful for something like /home so you have a full backup of your home directories without having to worry if some app has dumped its settings on a folder you don't have marked for backup. But also backing up / is useful because it gives you an easy recovery in the event of say disk failure. Just restore the entire system from a backup.
