For most people, a computer case is just a big, bulky box that’s hidden beneath the desk and out of sight. But it’s more than just that: It’s a critical component that safeguards the important (and expensive) internal components and facilitates their proper mounting and organization while promoting airflow, cooling and reducing noise.
Also called system unit, box or tower, computer cases come in different sizes and shapes based on the form factors of motherboards, power supplies and other hardware. They can be vertical or horizontal and are designed to house various other components, such as the CPU, GPU, hard drive and so on.
Most computer cases are built from rigid metals, often SECC steel and aluminium alloy. They usually feature a back panel with cut-out openings that expose I/O ports provided by integrated peripherals and expansion slots for additional I/O ports provided by external devices and cards. The case is also provided with various fans that can be connected to the motherboard and are used to cool the internal components.
The type of computer case you choose depends on the components you plan to install in your system and the available space at home or work. A full-tower case offers more potential for internal volume than a mid-tower or a mini-tower, and is the most suitable choice if you are building an extensive system that requires numerous graphics cards and other high-end hardware. The mid-tower case offers more flexibility than the mini-tower, allowing you to use a full range of motherboards and offering more options for fans to improve airflow. computer case
