My favorite memory of computer destruction happened last night. One of my suite mate's computers was broken beyond all repair, so we walked out on top of the 4th floor's roof, and dropped it down on to the asphalt. Needless to say... it didn't survive.
Another good story is when I worked at EchoStar over the summer. We shipped a PC to Europe for one of the groups there to use (it had all the software they needed preinstalled). We get a call about a week after we ship it. They received the PC, but the chassis was all bent out of shape, and it had dents. So the guy who called us (Nygel), bent the chassis back into shape, plugged it in (after changing the PSU's Voltage), and it worked like a charm. Amazing what a Dell GX110 can take.
