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.
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.
