Make anything cool with a Raspberry Pi?

I have a Raspberry Pi 3 Model B that I used to make a retro pi setup to play retro games. It works great. I also installed an OS on another SD card but I forget what it was called. I believe it’s a raspberry pi OS.

I didn’t get to it yet, but if I ever do something with my Pi again, I’ll turn it into an UrhoBox:

I JUST got a Raspberry Pi.

I’m hoping to turn it into a Plex media server. I was using an old laptop to do that but the hard disk died and I’m too loathe to change it.

Will share with you guys how the media server project goes
