    Cooler Master N-Series N300 USB 3.0 ATX Case Product Description

    The new Cooler Master N300 is a mid-tower designed for optimum cooling. There are four models to choose from by single / dual USB 3.0 support and side panel window. To keep constant cooling, the front panel is fully covered by mesh, and thanks to the SickleFlow fans, N300 generates extreme high airflow and keep silence for long-time operation. If you prefer liquid cooling solutions, installing 240mm or 120mm radiators in N300 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. Additionally, N300 supports up to 8 HDDs and high-end graphics cards up to 320mm / 12.6 inch for a plenty of expansion.
