Drop CSTM80 Barebones Mechanical Keyboard

With an innovative, interchangeable decorative top case, our CSTM80 Mechanical Keyboard is adding a new layer to the world of keyboard customization. Now, with the CSTM80 Barebones, you can add a few layers of your own. This stripped-down game-changer doesn’t come with keycaps or switches, so you can outfit it with anything of your choosing. It also doesn’t include the decorative top case, so you’ll get to select your favorite—or list of favorites—at checkout. Installation is ultra-intuitive: each top decorative top case fits magnetically—and seamlessly—onto the CSTM80’s specially designed polycarbonate case. It’s a breakthrough in the world of keyboard modifications, and we’ll be rolling it out in more than a few styles to match community-favorite keycap sets, colorways, and more. We’re also supporting the CSTM80 with a host of additional add-ons—including several keyboard weights and switch plates—to tailor your typing experience even further. Combine it all with a top-tier spec sheet, and you have a custom barebones keyboard ready to take center stage on any desk.

Understated, sophisticated, and armed with at least one trick up sleeve, the CSTM80 is the culmination of modern keyboard design, with a little disruption thrown in for good measure. That’s courtesy of the decorative top case—and while it’s certainly a disruptor in the keyboard space, it’s anything but disruptive on your desk. It attaches easily, securely, and inconspicuously; and it’s available now in several styles (and two materials), with many more to come. Around the top case, we designed CSTM80 with a refined aesthetic that’s both minimalist and classic. To this end, we choose the ever-popular tenkeyless layout, adding an extra F13 key for extra functionality and accent key real estate. We also chose south-facing per-key RGB lights to avoid keycap interference for unimpeded typing, with a sophisticated lightshow in tow. Creating your custom lighting experience—and well as your key commands—is both intuitive and in-depth, thanks to an STM32 chipset with QMK, VIA and Vial support.

The CSTM80 isn’t all looks and electronics. Under the hood—or rather, the top case—you’ll find a host of components designed to deliver an uncompromising typing feel. At its core, that feel starts with the polycarbonate inner case, specially crafted to securely hold the decorative top case and deliver just the right amount of flex for your typing. Inside this case, we’ve added in a custom gasket-mounted system with easily replaceable gasket pegs so you can easily switch pegs when changing plates. We’ve also installed a full array of foam—including PORON plate foam and case foam, IXPE switch foam, and a special silicone patch that fills out the bottom case and acts as a bottom gasket for the keyboard. Throw in the hot-swappable PCBA with south-facing LEDs for an enthusiast-preferred feel—plus a flexible polycarbonate plate and solid aluminum case weight—and you’ve got an exceptional typing experience, with plenty of room for customization.
