If you still have a plastic bin filled with every adapter for every piece of electronics you've ever bought sitting in the back of a closet.....
you're definitely trending old.
Garage actually, and it's a few pullout drawers and a knee-high cabinet. Last year a gtx 465? went to a cousin for his first computer build, and I had to fish through a handful of adapters/cables to find the right arcane mix to connect a new-ish macbook to an old monitor I had, also in the garage, for my BIL.
I've also made use of countless leftover screws, bolts, washers, and whatever else from all the random shit from China that's arrived at my household.
