Who it fits
Good fit for
This kit suits builders who want a full-size layout with a numpad and arrow keys. The gasket mount and hot-swap PCB appeal to those who enjoy tweaking their typing feel and sound without soldering. The large 4000mAh battery and triple connectivity modes make it practical for users who switch between devices or need long battery life. The screen and knob add utility for quick adjustments, making it a solid choice for office or gaming setups that value customization.
Who should skip it
You should look elsewhere if you need a pre-assembled keyboard. This is a barebones kit, meaning you must purchase switches and stabilizers separately. The full-size form factor requires significant desk space, which may not suit compact setups. Additionally, the screen and knob add complexity if you prefer a simple, minimalist interface. If you want plug-and-play functionality without the DIY effort, this option does not fit your needs.
Verdict: The ZMX GMK104 offers a versatile foundation for builders who value customization and a full-size layout. Its gasket mount and hot-swap features provide a solid base for a personalized mechanical keyboard experience.
ZMX GMK104 Key Specs Explained
Form Factor: Full-size
This listing provides a 104-key layout that includes a dedicated number pad and arrow keys. You get every standard key found on a traditional office keyboard. This format suits users who need numeric input for spreadsheets or data entry. It is larger than tenkeyless or compact designs. Choose this if you prefer a complete layout without missing any essential keys for your daily workflow or gaming needs.
Connectivity: Bluetooth 5.0, 2.4 GHz, USB-C wired
The kit supports three distinct connection modes for maximum flexibility. You can use Bluetooth 5.0 for wireless freedom with multiple devices, a 2.4 GHz dongle for low-latency gaming, or a USB-C cable for wired use. This variety allows you to switch between your computer, tablet, or phone easily. It ensures you can maintain a stable connection regardless of your environment or specific usage requirements.
Mounting Style: Gasket Mount
This structure uses gaskets and padding to suspend the PCB, rather than rigid screws. You will experience a softer, more cushioned typing feel that reduces finger strain. It also helps minimize harsh ringing sounds, creating a deeper tone. This design is popular among enthusiasts who prioritize acoustic quality and comfort. Compare it to plate-mounted boards if you prefer a stiffer, more direct feedback style.
Hot-Swappable
The PCB allows you to insert and remove mechanical switches without soldering tools. You can easily change the feel and sound of your keyboard by swapping switches. This feature makes DIY customization accessible to beginners. You can experiment with different switch types to find your perfect match. It saves time and money compared to traditional soldering methods, allowing for quick adjustments to your setup.
Design and Build Analysis
The ZMX GMK104 is a full-size mechanical keyboard kit. It measures 14 inches in length, 5 inches in width, and 1 inch in height. The listing states it weighs 1 pound. This mass provides stability during use. The gasket mount structure is a key design element. According to the listing, this setup includes silencing and cotton rubber pads. These materials cushion the typing experience. This choice helps reduce finger strain and minimizes noise. You can expect a softer feel compared to rigid plates.
The layout features 104 keys with no conflicts. You retain standard number keys, arrow keys, and function keys. This format suits office work and gaming. The kit supports hot-swappable switches. You can replace 3-pin or 5-pin switches without soldering. This feature allows you to customize the click and sound easily. The south-facing RGB LEDs ensure compatibility with most keycaps. You avoid interference from thick profiles.
Controls are integrated into the design. A metal volume knob provides tactile adjustment. A multifunctional screen sits above the keys. You can update and customize the display in real time. Two multimedia buttons flank the screen for backlight or display toggling. The listing notes compatibility with Windows and macOS. The finish is available in black or white. This build targets users who want to experiment with customization. You define the look and feel through your component choices.
Setup And Daily Use Guide
Setting up the ZMX GMK104 requires you to source your own switches, stabilizers, and keycaps. This is a barebones kit, meaning the PCB and case are included, but the tactile components are not. You install switches into the hot-swappable sockets. This process avoids soldering, allowing you to swap switches easily if you prefer a different feel. The gasket mount structure is built into the PCB assembly, so you do not need to assemble separate isolation pads. Once your switches are seated, you attach the keycaps and connect the device.
The keyboard supports three connectivity modes. You can use a USB-C wired connection for charging or low-latency input. Alternatively, you can switch to Bluetooth 5.0 for wireless use. The listing notes that pressing FN plus Q, W, or E switches between three paired devices. A 2.4 GHz wireless receiver is also supported for a stable wireless link. The 4000mAh battery provides extended usage time between charges.
For daily use, the kit offers full 104-key NKRO support. This ensures every key press is registered without conflict, which is useful for office tasks and gaming. You can customize lighting and macros using VIA software. The south-facing RGB LEDs work with standard keycaps. A metal volume knob and a multifunctional screen provide direct control over media and system settings. The keyboard is compatible with both Windows and macOS environments.
Before You Buy This Kit
You must source your own switches, stabilizers, and keycaps. The GMK104 is a barebones kit, so it arrives without the tactile components that define your typing experience. You will need to buy these separately to complete the build. This allows you to choose switches that match your preferred actuation force and sound profile. Check that your computer supports Bluetooth 5.0 or 2.4 GHz dongles for wireless use. The kit works with both Windows and macOS, but you may need to remap modifier keys for optimal workflow. Regular cleaning of the gasket mount and hot-swap sockets is recommended to maintain connectivity. This DIY approach suits builders who want control over every component. It sits alongside pre-built options by offering customization rather than convenience. You trade initial setup time for a personalized device.
Check before you buy
- Purchase compatible 3-pin or 5-pin mechanical switches.
- Source keycaps and stabilizers separately for the full-size layout.
- Verify your device supports Bluetooth 5.0 or 2.4 GHz.
- Check macOS key mapping for modifier keys.
