Back around 1981 I worked in a shop which had just taken delivery on an IBM 8100 system, a "mini-computer" about the size of a washing machine. We had an operator who weighed about 350lb (160Kg), and whenever this guy got within 10' (3m) of the thing it would crash. When the IBM FE came in, a circuit board was found to have a micro-fracture in it. Apparently whenever said operator got close enough, the floor would warp a bit, shifting the box enough to open a gap in the board.
