Neo80 CU - 80% TKL Aluminium Custom Mechanical Keyboard Kit

Neo80 Cu – 80% TKL with a Massive Copper/Brass Foundation and Stellar Design

The Neo80 Cu is built around the beloved 80% layout (TKL) – a proven favorite among professionals and enthusiasts who prioritize efficiency and functionality. This layout offers the perfect balance between compact design and practical usability, making it ideal whether you're upgrading your workspace or looking for a reliable daily driver.

At its core sits a distinctive, solid bottom case – available in copper or brass, combining striking visual appeal with substantial, satisfying weight. This foundation not only looks premium but also creates the ideal acoustic base for a crisp, pure typing sound.

Star Ring Accent Light

Inspired by massive celestial bodies whose gravity warps surrounding space, the top case of the Neo80 Cu features a multi-layered, illuminated "star ring" accent light – a planet glowing against the dark night sky.

The central "planet" is crafted from aluminum alloy with a triple-etched finish that resembles a rugged planetary surface. A surrounding stainless-steel piece with a mirror finish mimics the dark universe background. By elevating the planet slightly above the background, the design creates a stunning "floating planet" effect that adds depth to the board.

This contrast of materials and textures embodies romanticism in the industrial age: the matte, textured planet stands against the glossy, seamless dark sky – reserving a slice of the universe for your desktop.

Weight Design

Building on the extensive weight design of its predecessor, the Neo80 Cu takes the concept further by extending the weight all the way to the USB port area. This refinement showcases the harmonious blend of several materials – anodized aluminum, copper or brass, and stainless steel – with their complementary colors.

On the back, the intersection of the weight and the bottom case features a carefully sculpted slope that softens transitions. The compass-inspired Neo series logo sits in the center, underscoring the brand's iconic symbolism.

Beyond aesthetics, the weight combined with the bottom case brings the Neo80 Cu to approximately 4.5 kg. This substantial heft ensures exceptional stability and provides a solid foundation for its deep, clean sound profile with minimal vibration.

The Waistline

Viewed from the side, the top and bottom cases merge seamlessly with gentle curves. By avoiding sharp angles, the design creates an elegant, floating silhouette that perfectly balances the keyboard's substantial presence.

Mounting: Poron Gasket, Silicone Gasket & Top Mount

After extensive prototyping, a Poron gasket structure was integrated. Unlike traditional Poron gaskets that need to be glued to the case, special grooves in the bottom case hold the gaskets securely in place – allowing hassle-free replacement and excellent long-term durability.

The silicone gasket mount structure is retained as an alternative, and the Neo80 Cu additionally supports a top mount option for enthusiasts who prefer a stiffer typing experience. The gaskets and screws for all three options are included.

Acoustics: Forcebreak & Partitioned Chamber

Like most products in the Neo family, the bottom case features a strategically partitioned acoustic chamber that minimizes hollowness and unwanted resonance. Integrated forcebreak pads at all contact points between the top and bottom cases significantly reduce vibration and eliminate metallic noise.

Combined with the massive copper or brass foundation, this design delivers a deep, clean typing sound – without any foam. The signature Neo sound that the community loves.

Acoustic Package

While the Neo80 Cu already delivers a satisfying typing sound without any foam, every unit includes a complete acoustic package with Poron PCB foam, a PE sheet and case foam. You can keep the signature "no-foam" sound or customize your acoustic experience – full control over your keyboard's sound profile.

PCB, Hot-Swap & VIA

The Neo80 Cu is available for ANSI and ISO layouts. The PCB is non-flex-cut (1.6 mm), hot-swap-capable and VIA-compatible – so switches can be changed without soldering. Depending on the PCB variant you choose, the keyboard is purely wired (USB-C) or usable as a tri-mode board with Bluetooth and 2.4 GHz wireless as well. With a tri-mode PCB, two 2200 mAh batteries come pre-installed in the battery compartment and a 2.4 GHz dongle is included.

Note: The Neo80 Cu has no per-key RGB – lighting is limited to the star ring accent light.

Who is the Neo80 Cu for?

The Neo80 Cu is for anyone who wants to combine an efficient 80% TKL layout with the presence and sound of a high-end custom board. The massive copper or brass foundation, the partitioned acoustic chamber and the forcebreak pads create a deep, calm sound – ideal for long typing sessions at work as well as for gaming.

With three mounting options, VIA support and optional wireless, it adapts flexibly to different preferences. If you're looking for a stable, expressive desk centerpiece with a stellar design, this is it.

Note: The Neo80 Cu is a barebone kit. Switches and keycaps are not included and are available separately. The PCB and plate (per selection), stabilizers (NeoStab) and the complete acoustic package are included.
