From the manufacturer

Since our founding in 1992 as a thermal pioneer responsible for the first ever heat pipe heatsink, through our evolution into a manufacturer of cutting-edge cases and peripherals, to our recent groundbreaking switch to the modular format, Cooler Master has consistently rewarded its customers and fans with the utmost in innovation, choice, and control.

N400

ATX Mid Tower

The new Cooler Master N400 is a mid-tower designed for optimum cooling and expandability. The front panel and I/O area feature the premium mesh for a modern look. It supports up to 8 fans, including two pre-installed XtraFlo fans for extreme high airflow. If you prefer liquid cooling solutions, installing 240mm or 120mm radiators in N400 won’t be a problem as well – the 240mm radiator can be installed at the top or on the right side, and the 120mm one – in the rear.

N400 also provides plenty of expansion by support of up to 3 SSDs and high-end graphics cards up to 320mm / 12.6 inch. Max CPU Cooler Height 164mm / 6.4 inch Max GPU/PCI Card Length 320mm / 12.6 inch Supports a 240 mm water cooling radiator or two 120 mm fans on the right side or top of case Three dust filters (top, right side panel, and power supply) for easy maintenance
