A computer case is the box that houses most of your hardware components and connects all of the different wires. Also known as a system unit, base, enclosure or chassis, the case is the foundation of your computer and one of its most important parts, too.
It protects and shields all of the critical computer hardware from dust, physical impact, electromagnetic interference and more. This ensures the integrity of the hardware and prolongs its lifespan. It also helps with cooling and ventilation, preventing overheating that can damage the hardware.
Most cases also come with front-panel ports, which allow you to plug in and out peripherals like keyboards and mice without opening up the case. These ports may be slow USB 2.0s or combo headphone-microphone jacks, or they can be the latest-generation USB-C, HDMI and more.
The power supply is a critical component in the computer case that provides energy to all of the other hardware components. It is connected to the motherboard and other hardware components with cables, which can sometimes be a pain to work with when trying to upgrade or add new devices.
There are many different kinds of computer cases that are classified by their size and motherboard compatibility. These include mini-tower, mid-tower and full tower cases. Mid-tower cases are the most popular as they strike a good balance between price and upgradability. These typically have enough space to accommodate full-size video cards and two or three internal drive bays. computer case
