Mechanical Keyboard GLORIOUS GMMK 3 PRO 75% Barebones Wired USB, RGB, Black, 2 m cable

GLORIOUS GMMK 3 PRO 75% Barebones is a compact mechanical keyboard chassis in black designed for custom builds. This wired USB model with a 2 m cable uses a 75% form factor and a straight-style layout, and it is shipped without switches or keycaps to allow users to fit their preferred switches and keycaps. The keyboard features an aluminum CNC-machined top and bottom case, RGB LED multicolour backlighting, a modular internal design and support for MX-style 5-pin hotswap switches, enabling a tailored typing and gaming setup.

Advantages

The GMMK 3 PRO offers a solid, premium aluminum body for increased rigidity and longevity while remaining suitable for desktop use. Its high modularity lets users change plates, gaskets, switches and other components without soldering, providing extensive customization of sound, feel and appearance. Built-in sound-dampening foam and an aluminum switch plate help deliver a cleaner acoustic profile and balanced keystroke feedback. Native USB connectivity and a 2 m cable provide a reliable wired connection for stable performance.

How to use

Install compatible MX-style 5-pin switches and your chosen keycaps into the hotswap sockets following manufacturer guidance; no soldering is required. Connect the keyboard to a host computer using the included 2 m USB cable. Configure RGB lighting and any available firmware settings through the vendor's configuration tool or third-party software if supported. When assembling or modifying components, ensure parts are aligned correctly and secured to avoid damage to switch pins or the PCB.

Recommendations

For best results, use switches and keycaps rated for MX-style 5-pin hotswap sockets and handle the aluminum case and internal foam with care during assembly. If changing plates or gaskets to alter typing feel, test incrementally to find the preferred balance between firmness and flexibility. Keep firmware and configuration software up to date to access the latest lighting and macro features.
