PC Cases serve as protective enclosures for computer systems, particularly desktop computers. They house and safeguard the internal components of a computer, such as the motherboard, processor, memory modules, storage devices, and power supply unit. PC Cases are available in various sizes, designs, and materials to cater to different user preferences and requirements. Typically, PC Cases come with features like ventilation systems for cooling, cable management options, tool-less drive bays, and removable dust filters. They may also have multiple expansion slots for adding additional hardware components, such as graphics cards or sound cards. PC Cases are essential in maintaining the performance and longevity of a computer system, providing adequate airflow to prevent overheating, protecting internal components from physical damage, and offering a visually appealing design that complements the user's workspace.
