PC Case Zalman S4 Plus Midi Tower Black

The Zalman S4 Plus Midi Tower Black is a mid-tower PC case designed to combine a compact footprint with effective cooling and clear component presentation. The case features a front mesh panel to improve airflow and showcase RGB front fans, plus a full acrylic side panel that displays internal components.

Advantages

The front mesh design enhances intake airflow for more efficient cooling of internal components. Two pre-installed 120 mm front fans and one rear fan provide immediate ventilation out of the box. The full acrylic side panel offers a clear view of the build, while support for Mini-ITX, Micro ATX and ATX motherboards provides flexibility for different system sizes. Front I/O includes two USB 2.0 ports and one USB 3.2 Gen 1 Type-A port for convenient peripheral connections.

How to use

Install the motherboard according to its form factor (Mini-ITX, Micro ATX or ATX) and secure the power supply in the PSU area (power supply not included). Mount storage drives in the 3.5" or 2.5" bays as needed and connect front-panel USB and power/reset cables to the motherboard headers. Use the pre-installed front and rear fans for immediate airflow; add additional compatible fans or upgrades if required. Route cables behind the motherboard tray where possible to maintain airflow and maximize visibility through the acrylic side panel.

Recommendations

For best cooling performance, keep the front mesh unobstructed and maintain regular dust cleaning. When installing RGB fans, ensure proper cable management and compatible controller or motherboard headers to synchronize lighting. Verify PSU length and GPU clearance against the case depth before final assembly.
