The oldest tech I have are laptops from 2006, 2008 and 2009, a pc from ~2010 and an android phone from around 2012. I also have lots of newer stuff.

I've already built a home server from the most suitable pc. What other real use cases for old tech would you suggest? What is your experience?

Couldn't you just wire the GPIO to the solenoid (maybe through a relay if it needs higher voltage)?

(Or for that matter, use an ESP32 instead of wasting a whole Raspberry Pi on it?)
