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.
Minecraft server is always easy and fun. Honestly any game server.
You could use it to host a simple webpage too.
It would have to be a very old version of Minecraft. The recent ones take a lot of CPU power and RAM, even without mods.
It would probably work great for something like a Quake III or Unreal Tournament server though.
AFAIK the footprint is only slightly heavier than the old versions if you use the performance mods, not to mention these flags for the OpenJ9 JVM.
