I once witnessed a friend of mine friend of mine rip out a high-end and expensive surround 5.1 capable sound-card from his computer with his bare hands. Apparently because it didn't work for reason X, he got pissed and just went HULK-SMASH on it. He actually threw it out, through a closed window...
The rest of us were like 'Holy s**t, man! You're scaring us.'
In the end he calmed down, took up the manual and when he saw that he'd have needed to plug in an extra power cord for the card he almost wept, because he had just destroyed a perfectly functional and pricey sound card + two window panes for a problem that he could have fixed in about 20 seconds.
He did end up buying a new card of similar quality and take a few lessons in anger management from a psychologist.
