"Treasure" expands to fill the space available.

I tend to save this sort of stuff for a rainy day, but it never seems to rain. Really, you don't need more than one of a given type of item. It's been at least a decade since I've had a desperate need for a composite video switch. And, I still must have the end of that last roll of 5-conductor component video cable ... and there is that large box of composite video with audio patch cords.

An interesting way to get rid of the stuff is to offer a "buy the pound" (no warranties) sale. You'll have vultures show up and take stuff out by the carload.
