Elite 311 is our successor of our Elite 310 series, with an improved PSU placement for better cooling and cable management. Supports micro-ATX, and ATX motherboards. This chassis maintains Elite's pedigree of compact-sized and quality build that would look great in any space. There are 7 expansion slots and can accommodate a series of case fans for better cooling performance and airflow. It includes a 420W power supply to give a value added feature to the case.
