This is super neat even though it’s basically just running the main board plugged into peripherals - I already knew the main board was pretty small but it’s still surprising seeing it sitting on a table.
Makes me wonder what you could do with a case the size of a wii (or even a mini wii). Plenty of space for cooling, a 2.5" SSD bay, and I’m sure you could fit lots of other goodies in it too.
I’ve done a backup swap with friends a couple times. Security wasn’t much of a worry since we connected to each other’s boxes over ssh or wireguard or similar and used tools that allowed encryption. The biggest challenge for us was that in my selfhosting friend group we all prefer different protocols so we had to figure out what each of us wanted to use to connect and access filesystems and set that up. The second challenge was ensuring uptime and that the remote access we set up for each other stayed up - and that’s what killed the project as we all eventually stopped maintaining the remote access and nobody seemed to care - so if I were to do it again I would make sure all participants have alerts monitoring their shared endpoint.
