Neo75 CU - 75% Aluminium ISO/ANSI Keyboard Kit

Neo75 Cu – 75% Layout with a Massive Metal Bottom and Tool-Free Access

The Neo75 Cu is built around a compact, non-exploded 75% layout and puts a substantial metal bottom – available in copper or brass – front and center. As the debut of the Cu series, it combines substantial mass, an expressive design and a configurable internal setup into a high-end custom board.

Massive Copper or Brass Bottom

Massive metal bottoms have long been reserved for premium boards in the mechanical keyboard world – mainly due to high material costs and challenging processing. The Cu series was created to make this construction more accessible, and the Neo75 Cu marks its debut.

The metal bottom is the centerpiece of the design and is meant to shine from every angle. A curved facet on the side reveals the metal base between the top case and the battery compartment, and the striking color contrast is visible from the back and front as well. The bottom is available in copper or brass.

Design & Badges

Each kit includes a decorative badge that matches your chosen bottom material. You can position it in the top right or top left corner – or replace it with an extra key, based on your preference.

On the back, a circular accent badge serves as a design focal point in the Vortex style, available in gold, silver or black.

Ball-Catch Structure + Magnetic Connectors

The highly praised ball-catch structure with magnetic connectors is retained. You can tune your keyboard anytime, anywhere – without the hassle of cables or screws. Simply press and lift, and the case opens effortlessly, no tools needed.

Dual-Mounting System

Gasket mount: The gaskets have been upgraded once again – larger and thicker. They securely position the PCB and plate while minimizing potential horizontal shifts after assembly. They also reduce vibration transmission more effectively, which minimizes case ping and prevents vibration in foam-free builds.

Isolated bottom mount: Bottom mount and other hard-affixed structures have recently fallen out of favor, as they can affect typing feel and sound due to a lack of vibration absorption. However, the Neo75 Cu's high-density metal bottom effectively suppresses these vibrations – reviving this once-popular style in an improved form.

Gasket and bottom mount are combined innovatively by wrapping the mounting screws with gaskets. This eliminates unwanted noise caused by direct contact between internal components and the case, and ensures that the metal bottom's distinctive acoustic properties are fully expressed.

Be sure to try it out and experience the unique typing feel and crisp sound profile created by the combination of metal bottom and bottom mounting.

PCB Options – All VIA-Compatible

The Neo75 Cu is available with three PCB variants, each 1.6 mm thick, non-flex-cut, NKRO-capable and without per-key RGB:

• Tri-mode hot-swap: USB-C, Bluetooth and 2.4 GHz; supports ANSI and ISO
• Wired hot-swap: USB-C only; supports ANSI and ISO
• Solder: USB-C only; supports ANSI and ISO

Plates with Character

Your plate choice has a major impact on typing feel and sound. Four materials are available for the Neo75 Cu:

• Hard → Soft: carbon fiber → aluminum → FR4 → PP
• Clack → Thock: carbon fiber → aluminum → FR4 → PP

Note: the PP plate has one small hole near the spacebar.

Who is the Neo75 Cu for?

The Neo75 Cu is for anyone who wants to combine a compact 75% layout with the presence and sound of a substantial metal-bottom board. The tool-free ball-catch structure makes it especially appealing for tinkerers who like to swap switches on a whim and fine-tune their sound profile through PCB and plate choice.

With a tri-mode option, a dual-mounting system and VIA support, it adapts flexibly to different preferences – whether as an expressive desk centerpiece or a reliable daily driver.

Note: The Neo75 Cu is a barebone kit. Switches and keycaps are not included and are available separately. The PCB (of your choice), plate (of your choice), stabilizers (NeoStab) and the acoustic accessories are included.
