I recently replaced my old server (big case + i5-4590 8GB) with a new mini-PC (with a 5560U 16GB). The new one sips power and is so quiet in comparison. The 6TB HDD I had in the old one is currently just attached by a USB-SATA cable. I do intend to 3D print a mount for it to look a bit nicer, but you know what they say: there's nothing more permanent than a temporary solution.

I'm also trying Alpine + Podman on it instead of Ubuntu server + Docker. Most of it went without a hitch, though I do have an issue with PiHole not working because something called aardvark is using port 53 and Podman needs that running in order to work.

I also attached an old(ish) midrange phone to it with Termux for use as a low-power ARM server (just for playing around, really). I also intend to use it to test Rust code on ARM. I'm not sure what else to use it for though, so any suggestions are appreciated :)

Edit: Changed port 22 to 53, whoops.
