Mechanical keyboard GLORIOUS GMMK 3 PRO Barebones — Full-size (100%), Wired USB, RGB, Black

GLORIOUS GMMK 3 PRO Barebones — Full-size (100%), Wired USB, RGB, Black is a customizable mechanical keyboard chassis intended for home and office use. This full-size (100%) wired keyboard connects via USB and includes RGB LED backlighting and a 2 m cable. Supplied as a barebones unit, it arrives without switches or keycaps installed so you can fit your preferred mechanical switches and keycap sets for a personalized layout, feel, and sound. The chassis features a full aluminium body, modular construction and sound-dampening components that support a build-focused approach to performance and aesthetics.

Advantages

The barebones design allows full customization of switches and keycaps to meet individual typing preferences and gaming needs. A full aluminium body provides structural rigidity and a premium feel while built-in sound dampening foam reduces unwanted resonance. Nine points of modularity and a modular gasket system enable adjustments to typing characteristics and mounting options. The keyboard supports 5-pin MX-style hotswap sockets, making switch installation and replacement tool-free when compatible switches are used. RGB LED backlighting offers multicolour illumination for key legends and visual customization.

Suitable for

• Users who want to build a custom mechanical keyboard with preferred switches and keycaps
• Typists seeking a full-size layout with a numeric keypad
• Gamers who require wired USB connectivity for low-latency input
• Enthusiasts who value modularity and sound tuning options

How to use

Install compatible 5-pin or 3-pin MX-style mechanical switches into the hotswap sockets following the switch manufacturer’s instructions, then fit your chosen keycaps onto the switch stems. Connect the keyboard to a PC or Mac using the supplied 2 m USB cable. Use compatible configuration software to adjust key assignments and lighting: Glorious CORE 2.1 software is available for Windows and macOS and supports per-key programming and RGB control. If you plan to modify mounting or acoustic elements, follow service or assembly instructions and handle internal parts carefully to avoid damage.

Recommendations

Use only compatible MX-style mechanical switches when populating the barebones board. For long-term reliability, avoid forcing switches at an angle and ensure stabilizers and keycaps are properly seated. When adjusting modular components or swapping sound-dampening foam, perform changes on a stable surface and disconnect the USB cable before disassembly. For software configuration and firmware updates, download the official Glorious CORE 2.1 utility from the manufacturer’s site.
