My buddy built a PC for me in 2014. I've gotten a lot of use out of it, but for the last few years I've just been using it solely as a media server. Which it works fine for. But we are running out of space in our house and that thing is huge and loud, so I want to replace it with a Lenovo mini PC to work as my media server and use my external 5 TB hard drive for storage (I have a couple TBs just in pictures and stuff).

However, I realized I don't really know how to dispose of this old PC. I really don't want to generate a bunch of e-waste. I'd be happy to give it away but I can't imagine there's a way to get rid of an 11 year old homebuilt PC (good specs at the time, but still). I would be willing to pay a service to dispose of it in environmentally-responsible way, but I also feel like that you really need to know who you're giving it to since whenever I see e-waste sites pop up around town it always seems shady.

Suggestions?
