You can use a 3/4" Greenlee conduit punch, part no 72BB, for buttons. Someone also noted that Harbor Freight has a inexpensive set of knockout punches, item no 91201-5VGA, for $16. They also have a hydraulic version, item no 96718-1VGA, for $100 and for $29 you can get a 3" knockout that will "likely" handle 3" trackball openings. Good stuff.
