Nice, good luck there!
I tend to keep old computer parts. I also will take any and all old computers friends or family have because I don't care if they work. I scrap them for parts. That is how I got my server. I had some more or less functioning parts. A friends computer broke and they bought a new one. I got the old set (case and monitor). I am using the monitor as a second one, and those parts got scrapped for the server. I managed to put what I had together in a working (and apparently solid) computer.
I find it amusing (just because I can build them) that people will get rid of a computer because it stopped working, never realizing that all it needed was new RAM or a new CPU, or PSU, or HDD. Instead they go buy a new one and throw the old one away.
So I keep them, and build things out of them! I also use old (broken) parts as a display for stuff, kind of generates interest.
So keep it, it tends to work!
