Who it fits
Good fit for
This kit suits builders who want a compact 80% layout with modern connectivity options. You will appreciate the gasket mount if you prefer a softer, less harsh typing feel. The triple-mode connection helps those who switch between a PC, laptop, and tablet. The hot-swap feature is ideal for users who want to experiment with different switches without soldering skills. The included screen and knob add utility for those who like visual feedback and quick volume adjustments. It is a solid foundation for a personalized desk setup.
Who should skip it
You should look elsewhere if you need a complete keyboard with switches and keycaps already installed. This is a barebones kit, so you must purchase those components separately. If you prefer a fixed layout without a screen or knob, this design may feel too complex. Users who do not want to manage software for VIA programming or RGB customization might find the feature set unnecessary. Additionally, if you need a full-size numpad, the 80% layout will not provide the extra keys you require.
Verdict: The ZMX GMK87 offers a versatile foundation for custom keyboard builders who value connectivity and typing feel. Its gasket mount and hot-swap PCB make it a practical choice for DIY enthusiasts.

This compatibility with standard 3-pin and 5-pin MX-style switches gives you flexibility to customize your keyboard. It is ideal for builders who want to experiment with different switch types.
Mounting Style: Gasket Mount
Gasket mounts use flexible materials to hold the plate, reducing vibration and noise. This design typically creates a softer, more consistent typing feel compared to rigid screw-down boards. If you prefer a quieter, less harsh sound profile, this mounting style offers a distinct acoustic advantage. It is a popular choice for enthusiasts seeking better acoustics.
Design and build overview
The ZMX GMK87 measures 14.4 inches in length, 5.8 inches in width, and 1.6 inches in height. It weighs 1.5 pounds. The 80% layout keeps the number pad and function row while saving desk space. You get essential keys for typing and gaming without the bulk of a full-size board. This size suits users who want full functionality but need to conserve room.
The listing states it uses gasket mounting on the plate top to reduce vibration. This design choice aims to provide a softer, more satisfying typing feel by isolating the PCB from the case. You can adjust the typing angle using the dual-stage foldable kickstand. A convenient USB storage compartment is included for cable management. The finish comes in white or black with a metal knob and screen, according to the listing.
Controls include a dedicated metal volume knob and a TFT-LCD smart screen. You can customize the screen image, date, and time in real time. The kit supports hot-swappable switches for both 3-pin and 5-pin mechanical options. This allows you to change switches without soldering. The gasket mount and hot-swap features mean you can tailor the feel and sound of your keyboard. You build the experience by choosing your own switches and layout preferences.
Setup and daily use guide
You start by installing your chosen mechanical switches into the hot-swappable PCB. The board supports both 3-pin and 5-pin switches, including Cherry, Gateron, and Kailh variants. You do not need soldering tools for this step. Once the switches are seated, you can connect the keyboard to your devices. It offers three connection modes: Bluetooth 5.0, 2.4GHz wireless via a dongle, or a wired USB-C connection. The detachable cable allows you to charge the 3000mAh battery while using the keyboard in wired mode.
For daily operation, you can pair up to multiple devices, such as a laptop, tablet, or phone. The metal volume knob lets you adjust audio levels directly. The integrated TFT-LCD screen displays real-time information. You can customize the image, date, and time on this display. The keyboard also features south-facing RGB LEDs with 16 million color options. You control lighting speed and brightness using FN key combinations.
For typing comfort, the gasket mount design reduces case vibration. A dual-stage foldable kickstand allows you to adjust the typing angle. The base includes a compartment to store the USB cable. You can also program macros using VIA software. This setup gives you full control over key functions and lighting profiles without needing additional apps.
What You Need Before Buying
Because this is a barebones kit, you must purchase switches and keycaps separately. Verify that your chosen switches fit the hot-swappable sockets, which accept most 3-pin and 5-pin MX-style variants. You also need to ensure your keycaps use the standard stem profile to mount correctly on the installed switches. The included TFT-LCD screen and metal knob require no extra tools, but you should check that your operating system supports the VIA software for macro programming and RGB customization. Battery care matters for the 3000mAh cell; avoid deep discharges to maintain longevity. This kit suits builders who enjoy DIY projects and want a compact 80% layout with modern wireless options. It fits well alongside other gasket-mounted boards if you prioritize customization over plug-and-play convenience. Consider your desk space and device count before deciding, as the triple-mode connectivity handles multiple connections efficiently.
Check before you buy
- Buy compatible 3-pin or 5-pin mechanical switches for the hot-swap PCB.
- Source standard-profile keycaps that fit the switch stems securely.
- Confirm your OS supports VIA software for macros and lighting.
- Check if your devices support Bluetooth 5.0 or 2.4GHz dongles.
- Ensure you have a USB-C cable for charging and wired use.
