MSI MAG Forge 321R Airflow ATX Mid Tower Cabinet ( Black )

The MSI MAG Forge 321R Airflow is a full-size ATX mid-tower PC cabinet engineered to keep high-performance builds cool and visually striking. Its front mesh panel promotes unrestricted airflow into the chassis, channelling air efficiently over your components for stable, sustained performance during extended gaming or workstation sessions. Out of the box, the Forge 321R ships with four pre-installed ARGB fans — three 120 mm units at the front and one 120 mm unit at the rear — all connected to an onboard ARGB control board. The front-panel LED Switch cycles through nine lighting effects, giving you instant control without needing software. The tempered glass side panel puts your build's lighting on full display. Cooling headroom is generous. The case supports up to eleven system fans across the front (3×120 mm or 2×140 mm), top (3×120 mm or 2×140 mm), rear (1×120 mm), side (2×120 mm), and PSU shroud (2×120 mm) positions. Radiator compatibility extends up to a 360 mm AIO in the top and up to 240 mm at the front, making it straightforward to install an all-in-one liquid cooler alongside your existing fans. Hardware clearances are practical for modern builds. GPUs up to 390 mm long and 150 mm tall fit comfortably, covering large triple-slot cards including current 40-series designs. CPU cooler height clearance reaches 160 mm, accommodating most high-performance tower air coolers. The ATX power supply bay accepts PSUs up to 200 mm in length (when the HDD tray is removed). Seven expansion slots provide room for multi-GPU or accessory cards. Front-panel connectivity includes a USB 3.2 Gen 2×2 Type-C port running at 20 Gbps, two USB 3.2 Gen 1 Type-A ports at 5 Gbps each, and a combined mic-in/audio-out jack. Storage options cover one dedicated 2.5-inch bay plus two combo 2.5-inch/3.5-inch bays. A magnetic dust filter sits above the top vents for easy removal and cleaning without tools.
