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.
Thank you for reminding me to purge boxes again; It's probably time._ I will admit I do like to keep the ones with fancy artwork_.
The little plastic trays things come in (fans especially) though, those are worth their weight in gold. I always keep them for sorting things like twist ties, small wires, and tiny extra screws, etc in drawers.
