A solid foundation for your own build

Start with a full aluminium case and make the rest your own. The Hi75C’s powder-coated finish, compact 75% layout and multifunctional knob bring a substantial feel to a space-saving keyboard.

Add your preferred switches and keycaps to create a combination that suits your desk and the way you type.

Barebone only. Switches and keycaps are sold separately.

Built for a softer keypress

The gasket-mounted structure combines a polycarbonate plate with a 1.2mm flex-cut PCB for a softer, bouncier typing feel.

Four layers of dampening help manage internal resonance, while factory-lubed plate-mount stabilizers support smoother movement on the larger keys.

Choose your finishing touches: Different switches and keycaps will change the sound and feel of the completed build.

Connect your way. Make it your own.

Choose USB-C wired, Bluetooth or 2.4GHz wireless to suit your setup.

The hot-swappable PCB makes it easier to explore compatible switches without soldering. Finish your build with your preferred keycaps and customizable south-facing RGB effects.
