Neo Studio Neo80 Cu Custom Mechanical Keyboard with Tri-mode PCB

Full Copper & Brass Bottom

Despite its large 80% layout, we've maintained the Cu series's signature all-copper bottom design—bringing the keyboard's total weight to approximately 4.5 kg when fully assembled.

Acoustic Chamber Design with Integrated Forcebreak

Like most Neo keyboards, the bottom case features a partitioned acoustic chamber to minimize hollowness. Forcebreak pads at all contact points reduce vibration and metallic noise, and combined with the copper base, deliver the deep, clean "copper bottom" typing sound that Neo fans love, without any foam.

The Star Ring Accent Light

Inspired by massive celestial bodies, whose gravity warps surrounding space, the Neo80 Cu's top case features a multi-layered "star ring" light that captures the brilliance of a planet against the dark night sky.
The central "planet" features a triple-etched aluminum finish, surrounded by a mirrored stainless-steel ring, creating a striking "floating planet" effect.

Weight Design

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

Mounting Structure

Poron Gasket Mount + Silicone Gasket Mount + Top Mount

We've integrated the Poron Gasket structure into the Neo80 Cu. Unlike traditional Poron Gaskets that require gluing to the case, we've designed special grooves in the bottom case to securely hold the Poron Gaskets in place. This innovation allows for hassle-free replacement and ensures exceptional durability over time. Of course, we've also retained the silicone gasket mount structure as an alternative option for those who prefer it.

*Since the top-mount screws are fixed through the plate, choosing a solder PCB with a plateless configuration makes top-mounting unavailable

Plate Design: Research & Innovation

Glossy-chamfer ALU Plate Predecessor

Predecessor

After listening to our community, we designed a flex-cut aluminum plate for the Neo80 Cu. Early tests with single-key slots gave us uniform sound and bounce, but also a loose feel, pushing us to rethink the approach.

Iteration

Deep side grooves on the spacebar reduce harshness but could affect durability. To solve this, we added two spring-like supports that boost strength without stiffness. Paired with the flex cut, the design balances strength and flexibility.

Final Version

We added chamfers to every switch hole for easier installation, with glossy edges around the plate. In keeping with the celestial theme, we also incorporated a planet decoration above the arrow keys, creating a refined aesthetic from the inside out.

New PEI Plate

New PEI Plate

PEI is an emerging keyboard plate material that offers superior tenacity and stability compared to PC. It delivers a crisp sound and refreshing typing feel with every keystroke. Rather than using sandblasting, we apply a clear coating to create a smoother, more radiant finish that truly stands out.

New Color in Real Shots

Not only are we bringing back the fan-favorite Teal from the Neo series, but we’re also introducing a stunning lineup of fresh colors — Slate Blue, Taupe Grey, Dusty Rose, giving you even more ways to make your keyboard truly yours.

Mastery in Every Detail

Design is woven into every inch of our work, from the Star Ring Accent Light at the front to the compass-inspired on the weight. Within every small space lies an abundance of thoughtful artistry. We refine every detail with uncompromising precision.

Uncompromising in Materials

Every material choice is made with intention. From the harmony of an aluminum top case and copper bottom case to the introduction of multiple plate options, each element is thoughtfully considered. All to create a keyboard that feels truly your own.

Engineered with Purpose

Our structural design embodies our deepest commitment. The case features an Acoustic Chamber for refined sound, paired with an integrated force break to minimize unwanted resonance. With three mounting options, the keyboard can be tailored until it feels uniquely yours.
