The Mid-Tower Built for Builders Who Mean Business

The Corsair 4000D RS ARGB Modular Mid-Tower is engineered for the discerning South African PC builder who demands both thermal headroom and visual impact. Whether you’re crafting a whisper-quiet workstation, an aggressive custom loop showpiece, or your very first high-performance gaming rig, the 4000D RS delivers the flexibility, cooling capacity, and clean aesthetics to support your vision from first component to final boot.

Slide Into Perfect Airflow with InfiniRail™

Tired of fighting with fixed screw holes that never quite align with your radiator or cooling components? The InfiniRail™ Fan Mounting System eliminates that frustration entirely. Fans slide freely along a steel rail, letting you position them with millimetre-level precision — aligned to GPU hotspots, RAM clearance gaps, or radiator inlets exactly as your build demands. It’s a smarter approach to fan installation that saves time and opens up cooling configurations that traditional cases simply can’t match.

Dual 360mm Radiator Support for Relentless Cooling

The 4000D RS supports simultaneous dual 360mm radiator installations across three mounting locations: front, top, and side panel. This means you can dedicate one 360mm radiator to your CPU and another to your GPU, or run a single large-surface loop for maximum thermal headroom during extended gaming sessions and benchmark runs. With support for up to 13 x 120mm fans in total and compatibility with radiator sizes from 120mm through to 360mm, this case handles the most demanding liquid cooling configurations without breaking a sweat.

A Zero-Cable Showcase Through Tempered Glass

Pair the 4000D RS with a reverse-connector motherboard — ASUS BTF, MSI PROJECT ZERO, or GIGABYTE PROJECT STEALTH — and every power and data cable disappears behind the motherboard tray. What remains visible through the tempered glass side panel is pure hardware: your GPU, RAM, CPU cooler, and motherboard on full display, unobstructed by a single cable. Three pre-installed RS120 ARGB fans bathe the interior in customisable lighting right out of the box, making this case as much a showpiece as a performance platform. The included GPU anti-sag stabilisation arm keeps your graphics card perfectly level, protecting your PCIe slot and completing the polished look.
