I used to have so many cables, etc., that I didn't have room in the house for all the crap. I had 4 or 5 big bins completely stuffed with the stuff out in the barn. One day, I sorted through them; the transformers I saved for physics class - I figured they might come in handy as a non-variable low voltage power source some day. The cables - I kept one or two of any cable that had any chance of still being useful. Serial printer cables? Anyone still use those? To the landfill (electronics recycling container) they went. In the end, I had a very small box of wires, and at least 4 heaped over bins that I got rid of (over the course of a few trips; I never quite had the enthusiasm to clean them all out at once.)
