 Box of 10-32 rack screws, tap, and a battery powered drill/driver.

 Two or four of the screws run out from the inside, and nut them from the 
 outside. These serve as alignment pins and retainers.
 The rest simply screw into the taped panel from the outside, next to the
 old Dzus locations as Dana suggests. ( using star washers )
 Not as fast as Dzus fasteners, but cheap, easy, and effective.

 The conductive gasket isn't a bad idea, but make sure you do that
 with something with as low a resistance as possible, else you incinerate
 the gasket rather quickly. Those wool type things Harris uses are not bad.
 Me, I'd likely just wire brush the surfaces, maybe a coating of conductive grease.
