The Cooler Master Elite 300 is a Mini Tower chassis engineered for Micro-ATX and Mini-ITX motherboard builds. Its compact footprint is designed for space-conscious setups without compromising on core component compatibility. The case is constructed from a combination of steel and plastic and utilizes a conventional bottom-mounted PSU layout that supports standard ATX power supplies. A solid side panel maintains a clean and functional aesthetic for users who prioritize performance over internal component visibility.
For thermal management, the Elite 300 provides multiple cooling configurations, including support for up to 240mm liquid cooling radiators at both the front and top panels. It comes with a single 120mm fan pre-installed at the rear to establish baseline exhaust airflow. The interior offers clearance for CPU coolers up to 165.5mm in height and provides versatile storage options, including a 5.25-inch external bay alongside dedicated mounts for 3.5-inch and 2.5-inch drives. Features such as integrated cable management routes and a dust filter contribute to a cleaner and more efficient build process.
