Corsair is launching two new mid-tower cases designed for PC enthusiasts.

The Corsair Crystal Series 680X RGB is a high airflow ATX smart case that puts its RGB lighting on full display, with four included fans and a Corsair Lighting Node PRO for lighting control out of the box. The Corsair Carbide Series 678C is an ATX case emphasizing low noise and refined styling, with a plethora of cooling and storage options. Both are available in either black or white to fit any environment.

The Crystal Series 680X RGB case includes one Corsair SP120 fan and three Corsair LL120 RGB PWM fans, each equipped with 16 individually addressable RGB LEDs. Combined with the included Lighting Node PRO and Corsair iCUE software, the 680X RGB puts on a light show as soon you plug in your system.

Building on the legacy of Corsair’s Carbide Series Air 540, the 680X RGB uses a dual-chamber layout. The dual-chamber design ensures a Direct Airflow Path between the included cooling fans and your PC’s hottest components, directing cool air to where it’s needed most. In addition to the four included fans, the 680X RGB boasts room for up to eight 120mm fans and four simultaneous radiators (up to 360mm in front, up to 280mm in the roof and floor, and up to 140mm in the rear). Finally, a vertical graphics card mount lets you put your graphics card center stage – perfect for the 680X RGB’s three tempered glass panels in the front, roof and side that show off your components.

The Carbide Series 678C is a low noise case defined by its clean lines and smooth steel construction, styled with a single tempered glass side panel offering a window into your system. It is equipped with three Corsair SP140 PWM fans, a six-fan PWM repeater and high-density sound dampening material on the side, front, and roof panels to deaden the noise from your components.

With room to install up to nine 120mm fans and multiple radiators, including dual 360mm radiators, the 678C can accommodate a wealth of custom cooling to match the highest spec systems. A modular drive bay system allows the 678C to host storage and accessories, with room for up to 1x 5.25in drive, 6x 3.5in and 3x 2.5in drives, and the potential to add a further 2x 3.5in drives with additional trays.

Both the Crystal Series 680X RGB ($250) and Carbide Series 678C ($200) feature front panel high-speed USB 3.1 Gen-2 Type-C ports and are backed by a two-year warranty.
