The computer case is an enclosure for holding all components to form a proper system. All parts, like the Central Processing Unit (CPU), motherboard, hard disk, graphic and video cards, and cooling solution units, are connected through different cables and form a complex structure.
Its complicated circuitry structure requires an efficient frame unit to hold all these parts and reduce complexity. It helps in organizing and protecting all of the system units. So, if you are wondering what a computer casing is and why it is used, this article will explain your queries.
PC Cases
It is an enclosure that holds all the hardware circuitry components and is often called a chassis and base unit. Usually, they are made up of steel or metal. The edges of metal computer frames are very sharp, so be careful while working with them. The chassis depends on the form factors that determine its size.
In this article, we will help you understand what is computer case. Size consideration is significant when purchasing a new one. It should be compatible with the form factors of motherboards and other parts. Multiple companies like NZXT, Xoxide, and Antec are constructing high-end frames.
Why Do We Need A Computer Case?
Although we can assemble a PC without a PC case, but it will not look like a proper computer system. Remember that modern casing is more than a room to hold all the modules. So, consider all of its features before buying it.
Structure: According to the form of the case, all internal parts are organized. So, its build should be able to hold all of them in a compact design. Complex circuitry should be housed in an organized way, so you can effectively use them. There should be multiple USBs and other slots to connect peripheral devices effortlessly.
Protection: A basic need is to keep the system’s internal parts safe from all external damage. Protecting all of the elements is the main reason to get a frame. Dust, humidity, or some animals like mice, cats, and bugs can damage the internal parts. So enclosing it in hardcover is very important to avoid damages that the external environment can do. So get a system casing that offers you extensive protection against all odds.
Cooling: Cooling of the system is necessary. A computer is an electronic device that produces a lot of heat. There are special cooling units that are designed to cool down the system. However, it must provide efficient airflow to enhance the cooling performance. Some computer frames are designed to improve the airflow by containing venting holes that drive away the warm air from the system. Modern frameworks now offer more cooling by offering built-in fans.
Noise: Some internal hardware components, like fans, produce a lot of noise. So, enclosing them in a sealed cover reduces the noise level and offers you a noise-free experience. You can perform your activities and operations without worrying about annoying sounds.
Aesthetics: The casing is vital in delivering a unique aesthetic look for your system. You should buy a computer body that is aesthetically pleasing to your eyes as you will look at it for the whole day for a long time. So don’t ever buy an ugly one that delivers a dull look. The modern mounting structure offers you different looks with a classical style that upgrades the look of your system from boring to cool. They are available in different colors and some different stylish designs.
What Components Go Inside A Case?
The chassis holds multiple components that are the following:
Motherboard: It is a baseboard that holds all the components together and allows communication among them. The motherboard’s position depends on the system casing orientation and form factor. It is often attached to the bottom or side of the chassis. Its positioning is crucial as all elements must be directly linked. So before buying a mounting body, ensure its positioning is advantageous.
Central Processing Unit (CPU): The computer’s brain controls and manages all computer operations. It is a circuitry chip that contains an ALU and a control unit. Arithmetic and the logical unit perform all the mathematical functions, while the control unit is the supervisor of the system that controls all the actions. It usually lies on the motherboard.
Cooling Unit: All modern systems must contain a specially designed cooling unit that helps maintain the system temperature. These unit coolers include heatsinks and fans to draw the air away from the casing. So, there should be adequate room to mount them.
Internal Drives: There are multiple internal drives like hard drives, compact disk drives, etc., so it should have spacious space to mount them. There should be 2.5 inches, 3.5 inches, and 5.25-inch bays to mount the hard disks, floppy disks, optical drives, and other storage media. Usually, expansion bays are at the front side of the frame so they can easily reach out to the user, like CD drives.
RAM: Random Access Memory (RAM) is the primary storage. The data in processing is stored in this memory. During booting, the operating system is loaded on the memory. Different types of RAM are included in the frame related to system performance. RAM with a larger size offers increased performance.
PSU: The Power Supply Unit (PSU) is a module that provides power to all parts inside the carcass. This unit is responsible for converting AC to DC. It is usually located at the top back of it. In tower casing, it is positioned at the bottom back, and All-in-one is at the right back or left back of the frame.
Expansion Cards: These cards are known as adapters added to provide some additional capabilities like Video Graphic Adapters to deliver high-definition videos. Multiple expansion cards include interface cards, sound cards, network cards, etc.
Types Of Computer Cases!
The motherboard of the computers has different form factors that help determine the type of system chassis. So before buying a mounting body for your system, ensure it is compatible with the motherboard. These are the following types, so choose them accordingly.
Full Tower-ATX: It is one of the bigger form factors with a size of 24 inches. There is ample room to hold 6 to 10 drive bays and 11 PCI slots. It is one of the giant frames available nowadays and is also known as the full-tower. These can accommodate high-end motherboards and are primarily used for server systems.
Mid-Tower-MicroATX: It is a typical structure widely used for mainframe systems. These sizes vary from 18 to 24 inches and can contain 2 to 4 internal bays and 7 PCI slots. There are some additional 2 to 4 external bays used for peripheral devices.
Mini-Tower-Mini-ATX: The size of the mini-tower ranges from 12 to 18 inches. It can carry 1 to 2 internal bays with 3 PCI slots. There is little space to mount all the parts, so it has limited choices of component mounting.
Case Colors
The colors give a very modern and cool look to the system. They are available in colors like white, black, or other colors. The one with black color has a stylish and appealing look and is famous among gamers. Professionals use white color frameworks to give their system an elegant and sophisticated look.
Some users want a bright, colorful environment, so there are manufacturers to fulfill their needs. Computer bodies are also available in bright colors like blue, orange, pink, red, silver, and yellow.
What Are Computer Cases Made From?
The mounting structure is used to hold all of the delicate and complex elements. So, the chassis should be made of a specially designed material that fulfills its purpose. Usually, a hard substance like plastic and metal is used to make them. The customization option is also available, and you can customize the system frame of your desired material. There is an Apple I structure that is made of wood.
Conclusion
A computer is an electronic device that helps to perform actions efficiently. It is a complex structure comprising a CPU, hard disk, RAM, PSU, expansion cards, etc. They are all connected via various cables. Its intricate circuitry structure necessitates a robust casing unit that can accommodate all these parts while simultaneously reducing complexity.
The chassis’s size is determined by its form factors. It should be compatible with the motherboard and component form factors. Several companies, like NZXT, Xoxide, Antec, etc., make high-end structures. Different cases are available, like E-ATX, ATX, mini-ATX, and micro-ATX. You can choose your chassis according to your requirements.
However, remember that the motherboard and other components should be compatible with the case. You can also create a sophisticated look by choosing a colored casing with RGB lighting. Gamers and graphic creators widely use these types of frames.
