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?
A lot of modern receivers/integrated amplifiers have USB input. If yours has one, you can skip the crappy phone dac/amp and let the main sound system take care of it.
