Looks like some of the workstations our (old) parent corporation's IT department used to ship us. Stuffing them into a wrong-sized box with insufficient padding, then having them (mis)handled by FedEx/UPS as they got sent halfway across the country had predictable results. We had a couple arrive with the side panel off and the tower case visibly twisted out of whack, and one where the system had been bounced around hard enough that two of the DIMMs had come completely out of their sockets!
Amazingly, all of them still worked. I was sure the hard drives (at least) would be toast after that kind of abuse.
Edit: Inquiring minds also want to know... did it do that by itself, or did someone off-camera give it a little shove to get it rolling?
