Building a PC comes with all manner of little challenges.
Routing cables tidily is one thing, but fixing things damaged in transit is another, especially bent pins - Often trying to straighten them only bends them the other way and they snap, which is a heartbreaking experience when you've just dropped several hundred bucks on a processor that is now nothing more than a keyfob.
Some people suggest a self-propelling pencil, but I find a SAK toothpick so flexible that you can very carefuly apply just the right amount of force without bending the pin past the shear point. It's like using a tension wrench on a lock pick.
This example isn't a CPU, but it does have a bent header pin, courtesy of the previous user:
