Zalman S3 computer case Midi Tower Black

The Zalman S3 Midi Tower in black combines a hairline-finish metal front panel with dual intake openings and a full acrylic side panel to provide a balance of airflow and component visibility. The case supports Mini-ITX, Micro ATX and ATX motherboards and accepts both 2.5" and 3.5" drives, offering a compact yet versatile enclosure for typical desktop builds. Front I/O includes two USB 2.0 ports and one USB 3.2 Gen 1 Type-A port; the chassis does not include a power supply.

Advantages

The metal hairline front panel with dual intake improves air entry while maintaining a refined appearance, and the full acrylic side panel allows easy viewing of internal components. Compatibility with 120mm front and rear fans supports effective airflow configuration. The case accommodates common motherboard sizes and offers dedicated bays for 2.5" and 3.5" drives, providing flexibility for storage layouts.
