Case Zalman S3

Zalman S3 is a compact middle tower case in classic black color, aimed at budget and mid-range builds. It supports three main motherboard formats – ATX, Micro ATX, and Mini ITX, giving you freedom in choosing your platform. The internal space allows for a graphics card up to 330 mm and a CPU cooler up to 156 mm, so you can comfortably build a quite meaningful gaming or workhorse setup. The acrylic window provides visibility to the components without making the case unnecessarily bulky.

What you get is a well-balanced chassis with the capability for up to 7 x 120mm fans, which is more than enough for normal airflow in a mid-range configuration. The case comes with 1 x 120mm fan, so you can start your build right away and add cooling gradually. With a bottom-mounted power supply (up to 180 mm), cables are easier to hide and do not obstruct airflow. The support for basic water cooling – 1 x 120mm in front and 1 x 120mm in the back – gives you the option for an AIO on the CPU if you want a quieter system. Dust filters help keep the interior cleaner, especially if the machine runs daily.

• Support for motherboards ATX, Micro ATX, and Mini ITX, covering almost all mainstream gaming and office configurations.
• Form factor Middle Tower with dimensions 412 x 189 x 451 mm, providing a good balance between compactness and internal space.
• Capability for up to 7 x 120mm fans, offering flexibility for more serious airflow cooling with hotter components.
• Included 1 x 120mm fan, allowing you to start the build without immediately purchasing additional fans.
• Support for graphics cards up to 330 mm and CPU coolers up to 156 mm, sufficient for most mainstream gaming GPUs and taller air coolers from the budget and mid-range class.
• Bottom-mounted power supply, supported up to 180 mm, for better cable management and cleaner airflow; the case comes without a power supply.
• Acrylic window and dust filters, combining visual access to the components with easier maintenance and less dust accumulation.

Who it is suitable for: if you are looking for an affordable ATX case for a budget or mid-range gaming build, office machine, or home workstation, Zalman S3 provides exactly the basic things you need – enough space and meaningful airflow potential. It is not aimed at extreme high-end configurations with massive water cooling and huge radiators, but for a standard air build or compact AIO, it is completely adequate.

The most sensible thing about Zalman S3 is the combination of support for full ATX, enough space for standard components, and cooling options without unnecessarily increasing the overall cost of the build.
