System Unit

The Complete System Chassis

The System Unit is the structural home of the computer. Beyond looks, it provides mounting for every component, guided airflow, cable management, and protection from dust, static, and physical damage.

Real-World Usage

Chassis choice shapes the whole build: an airy mesh front feeds the fans, tempered glass shows off the interior, and drive bays determine how much storage you can install.

Interesting Fact

Some enthusiast cases are designed with negative-pressure layouts and dedicated channels for motherboard cable routing to keep airflow entirely unobstructed.
