Sparc 2's and 10's and 20's - I once had three piles, each about 20 high 
stacked in an airconditioning/pipework room (since the building had run 
out of storage). Fortunately, they were centred on the single tile that each 
pile stood on and each pile was leaning against the room wall.

Manager comes in, looks despairingly at the neat piles and says quietly

"You do realise you're almost certainly exceeding the point loading of 
the floor"

and walks out :)
