Just cleaned out mt garage, closet, and attic. No clue why I kept every single box of anything electronic/tech based in the last ten years. I just tossed boxes for phones I haven't had in years, old CPU and heat sync boxes, boxes for 100mbps nics, old modems I don't have anymore. I've never needed any of these and have brought them with me through too many house moves.
I keep it in case i have to sell it as it has more value with the box. Same goes with collectibles and such...
I said the same thing years ago and then was too lazy/never got around to selling anything.
I had the start of a hoard going, was good for me to get rid of it.
