GATERON Castle IG98 Mechanical Keyboard, Tri-Mode, Hot-Swappable, RGB, PBT Keycaps

Choosing a keyboard for a single computer is different from setting up a workspace shared across several devices. The GATERON Castle IG98 supports both kinds of routines with wired and wireless connection options.

Its 98-key layout keeps a broad set of keys within reach, while tactile Mini i switches provide a mechanical feel for everyday typing and gaming.

RGB backlighting adds customizable color to your desk, and hot-swappable sockets make switch changes part of the keyboard’s flexible setup.

The essentials

The Castle IG98 combines a 98-key QWERTY layout with tactile Mini i switches. That makes it suited to a mix of work, writing, and gaming, with a mechanical key feel as you move between tasks. RGB backlighting lets you personalize the keyboard’s appearance, while the included PBT keycaps add a clearly specified material detail to the setup.

Connection choices are a practical differentiator. Use USB-C for a wired connection, Bluetooth across three channels, or 2.4 GHz wireless through USB. The combination supports a workflow across up to five devices, which is useful when moving between a computer, laptop, tablet, or other compatible device. Windows and Mac compatibility is highlighted, and the manufacturer also lists Android and iOS.

Hot-swappable sockets support both 3-pin and 5-pin switches. That gives switch customization a straightforward role in the keyboard’s setup, without requiring the user to commit to a single switch configuration. N-key rollover is also listed for the keyboard.

How to use it

Choose the connection that suits the device and desk arrangement: USB-C for a direct wired setup, Bluetooth for a compatible wireless device, or the 2.4 GHz USB connection. With three Bluetooth channels alongside the 2.4 GHz and wired options, the keyboard can serve a multi-device workspace rather than being tied to just one connection style.

For a more tailored typing feel, the hot-swap sockets accept compatible 3-pin and 5-pin switches. RGB lighting provides another way to adjust the setup, with color and lighting effects available for a personalized look. It’s a great fit if you want a keyboard that can adapt to both your connection preferences and your preferred switch setup.

Best use cases

For a desk used for both work and play, the tactile switches and 98-key layout support familiar typing alongside gaming sessions. The RGB backlight can add color to a gaming setup, while the same keyboard remains suited to daily computer use.

The multi-device connections are especially useful when a laptop, desktop, or tablet shares one workspace. Bluetooth channels, 2.4 GHz wireless, and USB-C provide different ways to connect as the setup changes. Compared with choosing a keyboard around a single fixed connection, this model offers more options for a desk where devices and tasks vary.

Switch enthusiasts can also make the hot-swappable design a priority. Support for 3-pin and 5-pin switches makes it possible to customize the switch configuration, while keeping the keyboard’s existing layout and RGB lighting as part of the setup.
