This Floppy Drive is fitted in my System 5, its in a 34HP wide, 160mm deep, 4U high module, this is definitely non-standard and needs to be custom made from a larger module/panel. It takes just two 145 x 100mm aluminium panels fitted between the top and bottom guide rails to attach the drives to. The gap between the panels is then exactly the same as a 5.25" Floppy Drive. There is not sufficient space on the front panel for a handle. Because of the non-standard size of this module no rear panel is available so I fabricated my own.
