Yes, machines that had tape drives that swung out on hinges 
or big removable pack hard drives on chassis slides might 
have this.  The PDP-11/45 had outriggers that were attached 
to the front of the rack before you could roll the CPU out 
for maintenance.  (Generally left permanently in place, but 
removed when shipping the unit.)
