COOLER MASTER 310C ATX Mid Tower Cabinet ( Black )

The Cooler Master 310C is a black ATX mid tower cabinet designed for builders who need a practical, well-ventilated enclosure without unnecessary complexity. The chassis accommodates both standard ATX and Micro-ATX motherboards, making it a flexible choice for a range of build configurations across different budget levels. The front panel features a mesh bezel that promotes passive airflow into the chassis, supplemented by an optional 120mm fan position at the front for active intake cooling. A pre-installed 120mm fan at the rear ensures continuous exhaust airflow to keep internal temperatures in check. An additional optional fan position on the side panel—supporting 80mm, 90mm, or 120mm fans—can provide direct cooling to graphics cards. A top-mounted dust filter helps reduce particle accumulation on internal components. Storage flexibility is a standout practical feature of the 310C. The case offers three exposed 5.25-inch drive bays, one exposed 3.5-inch bay, and five hidden 3.5-inch bays, giving builders ample room for optical drives, hard drives, and related peripherals. Seven expansion slots provide sufficient room for full-size graphics cards, sound cards, and other PCIe add-in boards. The front I/O panel includes one USB 3.0 port, one USB 2.0 port, a microphone jack, and an HD audio output—all positioned for convenient day-to-day access. A side panel security lock adds a layer of physical protection for your components. The 310C accepts a standard ATX PS2 power supply and fits graphics cards up to 283mm in length and CPU coolers up to 158mm tall, covering a wide range of mainstream cooling and GPU options. — Verified Specifications — Model / P/N: RC-310C-KKN3-U3 Form Factor: ATX Mid Tower Motherboard Support: ATX, Micro-ATX Materials: Steel body, ABS plastic, mesh front bezel Dimensions: 477 × 190 × 446 mm Color: Black Expansion Slots: 7 Drive Bays: 3 × 5.25" (exposed), 1 × 3.5" (exposed), 5 × 3.5" (hidden) Front I/O: USB 3.0 × 1, USB 2.0 × 1, Mic × 1, HD Audio × 1 Fan Support: Front 120mm × 1 (optional), Rear 120mm × 1 (installed) + 80/90mm × 1 (optional), Side 80/90/120mm × 1 (optional) Max GPU Length: 283mm Max CPU Cooler Height: 158mm PSU Type: Standard ATX PS2 Dust Filter: Top Warranty: 2 Years
