GMK104 Mechanical Keyboard Kit with Screen & Knob - Full Size DIY

Our review of the GMK104 Mechanical Keyboard Kit finds it aimed at builders who want a full size, customizable board with multimedia flair. The single biggest reason to buy is the integrated smart display and metal volume knob, which turn a barebones, gasket-mounted, hot-swappable 104-key platform into an interactive centerpiece for a desk. For tinkerers who value programmability and long wireless runtime, this kit blends VIA support, three-mode connectivity, and a 4000mAh battery into a package designed for both office use and gaming.

Key Features

• Smart Display and Controls: The multifunctional screen can be updated with custom images and is paired with two multimedia buttons that switch backlight or screen on and off for quick control.
• Metal Volume Knob: A tactile metal knob gives smooth, hardware volume control that feels durable and precise during media playback or game sessions.
• Full 104-Key NKRO: The standard 104-key layout includes numpad and function row with NKRO to ensure all simultaneous keypresses register for gaming and productivity.
• VIA Programmable: Full VIA support lets users remap every key, build macros and customize lighting without reflashing firmware, speeding up the DIY workflow.
• Three-Mode Connectivity: Switch between Bluetooth 5.0, 2.4GHz dongle, and USB-C wired modes, and pair three devices for quick context switching with FN shortcuts.
• Gasket Mount & Hot-Swap: Gasket mounting plus silicone padding provides a cushioned, quieter typing feel while hot-swap sockets accept 3-pin and 5-pin switches for easy customization.

Who It's For

The GMK104 is best for enthusiasts who want a full size, buildable keyboard with advanced features like VIA programmability, a user-updateable screen, and hardware media controls. It suits users who plan to swap switches, experiment with layouts, and value a standard number pad for spreadsheets or gaming macros.

Those who prefer a pre-assembled, out-of-the-box experience or who need ultra-compact layouts should look elsewhere, since the GMK104 is a barebones DIY kit that expects users to add switches and keycaps and to perform basic customization steps.
