When I wanted to build a new rig, I'd find a family member who could use the old one. I've run out now though, so it's a good thing my current rig(s) should still have a few years left in them (with upgrades, of course). Parts from upgrades accumulate until there's [almost] enough to build a new one, then I buy whatever's missing, build the rig, and give it away. The last one went to the Shelter Animal Rescue Group from which my wife and I got two excellent kittens.
Anything broken or useless I take to a recycling place.
