ATX Mid Tower for Custom Builds

The Zalman S4 is a steel and plastic mid tower that accepts ATX, mATX and Mini ITX motherboards, with seven expansion slots and drive bays for one 3.5 inch and three 2.5 inch devices. A full tinted acrylic side panel shows the interior while the grey exterior carries a black coating for corrosion protection. The bottom mounted power supply layout keeps cables tidy. Note that ATX boards with lower right side mounted SATA connectors are not compatible.

Thermals, Noise and Power Draw

Two 120mm sleeve bearing fans are preinstalled at front and rear, each running up to 1200 RPM with 28.34 CFM airflow at 23.2 dB(A). The front panel bezel is shaped for intake and the case supports up to three front, two top, one rear and two bottom 120mm fans. Radiator mounts allow 120mm or 240mm at the top and 120mm at the rear for liquid cooling. Maximum CPU cooler height is 160mm and maximum power supply length is 180mm.

Build Quality and Daily Connectors

The steel chassis with plastic accents uses a premium black coating for durability. Front I/O provides USB 3.0, USB 2.0 and HD audio ports for everyday peripherals. Dust filters are fitted to help keep the interior clean. Graphics cards up to 315mm fit without obstruction. The tinted acrylic side panel is secured for easy access during upgrades or cleaning.

Questions about this item

How do I mount the pre-installed 120 mm quiet fans, and which step is commonly missed?

The front and rear 120 mm quiet fans are already fitted. The step often missed is removing the protective film from the acrylic tinted side panel before securing it, otherwise the panel scratches during installation.

Which dust filters will need cleaning or replacement over time?

The case includes dust filters on the front, top and bottom intakes. All three should be removed and cleaned periodically to maintain the 28.34 CFM airflow rating of the 1,200 RPM sleeve-bearing fans.

What is the first thermal limit reached when the CPU and GPU run sustained loads?

The CPU cooler height is capped at 160 mm, so tall tower coolers cannot be fitted. That restriction limits the maximum heat dissipation before the 120 mm rear exhaust fan becomes the bottleneck.
