I built my PC like 8 years ago or something, and kept all the boxes for the spare parts for like 7 years and never needed them, so eventually during spring cleaning I just chucked them out. I was like “this big box of boxes does not spark joy.”

And then… that’s when I finally need a spare part. Today I go to install a second M.2 drive and realize I have no spare motherboard screws on hand.
