Drop CSTM65 Mechanical Keyboard

With the CSTM80 and its interchangeable decorative top case, we made a big statement in the world of keyboard customization. Now, with our next member of the CSTM family, that statement’s staying just as big—but the board itself is getting quite a bit smaller. Introducing the CSTM65: a compact enthusiast desktop centerpiece made for game-changing customization. The game changer? An innovative new component, purpose-built for personalization. We’re calling it the decorative top case, and it fits magnetically—and seamlessly—onto the CSTM65’s specially designed polycarbonate case. It’s a breakthrough in the world of keyboard modifications, and we’re rolling it out in more than a few styles to match community-favorite keycap sets, colorways, and more. At launch, we’re also supporting the CSTM65 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 compact, custom keyboard ready to take center stage on any desk.

Understated, sophisticated, and armed with at least one trick up sleeve, the CSTM65 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 CSTM65 with a refined aesthetic that’s both minimalist and classic. To this end, we choose the space-efficient 65% layout, complete with arrow keys for functionality that doesn’t compromise the compact footprint. We also opted for sleek ABS keycaps with front-facing, laser-etched shine-through legends to complement the community-requested south facing per-key RGB lights. Creating your custom lighting experience—and well as your macros—is both intuitive and in-depth, thanks to an STM32 chipset with QMK, VIA and Vial support.

The CSTM65 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 fits 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 configuration—plus a flexible polycarbonate plate and solid aluminum case weight—and you’ve got an exceptional typing experience, with plenty of room for customization.
