The MKC75 Keyboard Kit is a versatile and high-quality 75% custom keyboard kit that offers enthusiasts a high degree of customizability, stability, and performance in a compact format. The fully CNC-machined 6063 aluminum chassis not only provides a robust foundation but also a premium look and feel. Thanks to its three-in-one structural system, the kit can be assembled as a top mount , plate gasket mount , or PCB gasket mount – ideal for different typing and sound preferences. Support for tri-mode PCBs (wired, Bluetooth, and 2.4 GHz wireless) makes the MKC75 a flexible solution for desktop, laptop, and mobile setups. Furthermore, compatibility with QMK/VIA firmware is ensured in wired mode, allowing for extensive customization of key mappings, macros, and other functions. Overall, the MKC75 delivers excellent value for money in the budget-premium custom keyboards category.
