What are the chassis form factors?

Chassis form factors refer to the physical specifications and dimensions of computer cases or enclosures, which determine compatibility with internal components. Common form factors include ATX, MicroATX, Mini-ITX, and E-ATX, each varying in size and layout to accommodate different hardware configurations. They influence factors like airflow, expansion slots, and overall system aesthetics. Choosing the right chassis form factor is essential for ensuring that all components fit properly and operate efficiently.
