If you're looking for a fun use for your shelved rpi, I can recommand installing a retro-gaming distro such as recalbox (https://www.recalbox.com/) or retropie (https://retropie.org.uk/).

I installed recalbox on a rpi3, and it runs nes/snes fine, and even some n64 games. On occasions I brought it along when visiting friends, and plugged it into the TV/projector with a couple of joysticks. It has been a blast!

All in all I'm very happy with my small on-the-go arcade machine.
