It’s not worth shipping and handling, it’s beaten up, and I don’t know anybody who wants it. Nothing is upgradeable, unless you count inserting a microSD card.
Of course I could use it as a janky media server or a dumb SSH terminal, but I’ve already got other machines for those jobs. Or I could recycle it, but what’s the fun in that? Suggest me your wackiest programs to try, dangerous distros, or most unorthodox setups to make use of it.
Server for various open source games that don’t require much cpu or ram. E.g. freeciv, battle for wesnoth.
You could turn it into a Home Assistant control panel if it has touch screen support
See if it runs either Menuet OS or Kolibri OS, they’re about the smallest non-linux OSs I know of.
If it’s an asus ee, the vents are all on the sides. With a couple of shims underneath it would fit in a bookshelf with a bunch of other books.
As far as uses… nat hole punching for an overlay network is one way I’ve used these devices before.
Batocera linux and retro games!
Try to flash Coreboot on it.
As a TV for your kitchen?
If it has an ethernet port (or perhaps a USB to ethernet dongle), maybe a PiHole DNS using Debian or the like? It is apparently supported on other Linux distros than Raspbian.
If it supports micro SD XC (i.e. capacities higher than 32GB) or you have a USB hard drive or high capacity USB flash drive, maybe a samba server for file storage? I often use my file server as a substitute for digging out a flash drive any time I want to quickly pass a file between two machines in my house.
Nothing. Power waste and it doesn’t do much.
Home Assistant host MAYBE, but you can find lesser power straws to run that.
