The CORSAIR FRAME 4000X RS is a mid-tower built on the FRAME modular system, with a high-airflow front panel carrying built-in ARGB lighting under motherboard control. Four RS120 PWM fans are pre-installed, three separate 360mm radiator positions are available, and graphics cards up to 405mm fit with the front fans in place.

The RGB Flow front panel builds the lighting into the ventilated grille rather than relying on lit fans behind it, and it is driven from a standard motherboard ARGB header. The included RS120 fans are plain PWM units, so the illuminated element is the panel and airflow comes through it unobstructed.

The FRAME modular case system uses interchangeable parts, so front panels, side sections and accessories can be changed later without replacing the chassis. That makes the look of the build adjustable after purchase and lets the cooling layout be reconfigured as the hardware inside it changes.

Four RS120 PWM fans come pre-installed as intake, using magnetic dome bearings to cut friction and hold airflow at a low noise level. They are daisy-chainable, which keeps the header count down, and the case supports up to thirteen 120mm fans in total for a fully populated build.

The InfiniRail fan mounting system replaces fixed screw holes with a rail, so fans between 120mm and 200mm slide along it to whatever position suits the build. Fans can be placed to clear a radiator, a tall memory kit or a long card instead of being locked to preset holes.

There are three dedicated 360mm radiator locations in the front, roof and side, and two of them can be populated at the same time. The roof additionally accepts 280mm and 240mm sizes, and the rear takes a 120mm or 140mm fan, with CPU air coolers up to 170mm tall supported.

The front panel provides one USB 3.2 Gen 2x2 Type-C port, two USB 3.2 Gen 1 Type-A ports, a combination audio and microphone jack and the power button. Two Type-A ports means a headset and a peripheral can stay connected without occupying the faster Type-C connection.
