Cooler Master N400

The stylish PC mid-tower attracts attention by its industrial design and a front blue LED fan. N400 excels in efficient cooling and various possibilities to expand its features. In addition to the two high-quality 120mm fans, you can add up to six fans to provide sufficient cooling even for the most powerful components. The left side panel is adapted for mounting a water cooling radiator. The PC case comes equipped with dust filters.

The case has a firm steel structure and a front plastic panel which features headphones, microphone, USB 3.0 and 2.0 connectors. The PC case has two 5.25" bays and several 3.5" and 2.5" bays. The spacious black interior of Cooler Master N400 supports ATX and microATX motherboards as well as the longest graphics cards, such as NVIDIA GeForce GTX690.
