Manufacturer description
The Zalman S3 is a budget ATX mid-tower built around airflow rather than flash. Three 120mm case fans ship pre-installed out of the box, and Zalman's optimized cooling layout lets you mount up to eight fans total if you want to push more air through the chassis. A full acrylic windowed side panel shows off the build, while the hairline front panel and dual intake design with metal finish give the front face a cleaner look than most cases in this price bracket. Dual-line front ventilation with metallic decoration feeds the intakes, and top plus bottom dust filters keep circulation smooth…
