Shipping a computer
A friend of mine that lives in another state, decided to send one of his unused computers back to one of his relatives, he reformatted and packaged all the discs and papers in a single box, the old Pentium 4 socket 478 HP case was wrapped in protective foam to ensure it would not get damaged during transport, and shipped it off expecting nothing to go wrong.
Something did go wrong
Upon arrival his relative noticed a funny rattle like sound coming from inside the box, and as the box was moved from side to side, it felt as tough there was something heavy "loose" inside, beeing a care full person, the relative contacted my friend about the issue before trying to plug it on, to which he promptly asked to open the box and open the case door, and they where surprised to find "a big piece of metal with a fan, hanging from the inside of the computer, and the metal had a part full of copper pins all bent and warped"
