Zalman S3 Midi-Tower Case with window, Black

The Zalman S3 is an ATX mid-tower case designed for standard PC builds, supporting ATX, Micro-ATX, and Mini-ITX motherboards. Its structure combines steel and plastic, with a full acrylic side panel for viewing internal components. The case measures 189 mm in width, 451 mm in height, and 412 mm in depth, maintaining a conventional footprint for this form factor. The design prioritizes core functionality with a clean, black finish suitable for various environments.

For thermal management, the chassis provides multiple mounting points for 120mm fans at the front, top, rear, and bottom. A single 120mm fan is pre-installed in the rear exhaust position to establish initial airflow. Liquid cooling is supported with mounts for 120mm radiators in several locations. Key component clearances include a maximum CPU cooler height of 156 mm and a maximum power supply length of 180 mm, which should be referenced to ensure compatibility.

Storage options consist of dedicated bays for up to two 3.5-inch drives and two 2.5-inch drives. The front I/O panel includes one USB 3.2 Gen 1 Type-A port, two USB 2.0 ports, and separate microphone and headphone audio jacks. The rear of the case is equipped with seven standard expansion slots for graphics cards and other add-in cards. A bottom-mounted PSU bay is utilized for power supply installation.
