The bottom case for the SixtyFive comes available in a variety of distinct options. Ranging from anodized, e-coated, or electroplated aluminum to CNC milled and sandblasted polycarbonate, offering a glance into the keyboard’s internals while also allowing the RGB underglow light to pass through. Brass and copper options substantially increase the board’s heft.

SixtyFive extra bottom cases each include a set of grey feet.
