What is Cabinet in Computer System With Examples and Diagram

Introduction
In today's post, we will learn What is cabinet in computer system with examples and diagrams. We will also learn types, uses, and functions in easy-to-understand language and computer terms.

The computer cabinet is a square shape box that allows various other hardware devices and components to allow them to set up inside the computer system cabinet.

Some years ago, these computer cabinets used to come in huge shapes and sizes.

But as the technology developed, the need for smaller and lighter cases came into demand, forcing the manufacturer to build small chassis.

Nowadays, the case comes in approx—500 GM to 1 KG. 

These cabinets are pretty attractive, and a few extra layers of slots are available to install a few more computer hardware devices and components to improve and enhance the overall look and feel.

These cabinets are manufactured to provide an extra layer of security, which we will discuss further in the article.

What is Cabinet in Computer System With Examples and Images

The computer cabinet is nothing but an enclosure that allows other computer parts to be installed inside them; such parts are Motherboard, Computer hard disk drive, SMPS, RAM, Optical Drives, Processor, etc.

The computer cabinets are also called "Chassis", "Computer case", "Computer Box" and so on.

The Computer cases or chassis are available in different shapes, colors, sizes, and cool features.

As we have discussed earlier, all computer motherboards are installed inside the computer cabinet with the help of screws and pre-drilled holes.

There are USB and audio slots on the front side of the cabinet to provide additional comfort and feature to enhance the product usability.

There are some slots available in the cases that are removable after attaching optical drives into the system.

The backside of the case is used to attach a power cable inside the power section or SMPS {Switch Mode Power Supply} which provide voltages to the computer system to function.

The main objective of the SMPS is to convert A.C. power to D.C. as the computer system operates on D.C. power supply; later, the voltages are transferred to other parts of the computer system through the motherboard.

These computer cabinets are made up of fiber, plastic and iron-like materials.

The cabinet’s primary purpose is to attach all the parts of the computer system inside the chassis.

All the computer parts are delicate and can get damaged if left outside. Therefore, it is advised and recommended to collect them and install them inside the case.

The cabinet also possesses connecting ports and buttons. They are used to connect the keyboard, mouse, printers to the motherboard.

The cabinet’s main advantages are that it protects all the sensitive and essential parts of the computer system from water, dust, and physical damage, as the parts are safely assembled inside the computer cabinet.

The cabinets are selected keeping in mind your usage and computer parts, especially the motherboard. There are different types of motherboards available in the market.

Not all motherboards can be fitted or installed in all cases. There are different cases designed and developed for the different motherboards.

For Example, Gaming Motherboard is not compatible with AT cabinets.

These differences in shape, design, and dependency are called “Form Factors”, which we will discuss further in the article.

4 Different Types of Cabinet in Computer System?

The cabinets are broadly classified into three different types, which are as follows.
  • Desktop Cases
  • Tower Cases
  • Notebook Cases
Types of Cabinet in Computer
Types of Cabinet in Computer
The Desktop Cases

The personal computer uses desktop cabinets or cases designed and developed to sit flat on the desk, and the monitor was used to be placed upon them.

The chassis was small and compact. They are old fashion cabinets hence no more used and are obsolete from the market.

Tower Cases

They are 2 to 3 feet in height and used to be placed upright on the desk. They are used on a desktop personal computer.

The tower case is further classified. 

Mid-Sized Tower Cabinet called mid-towers are most used and famous.

These cabinets are used for various motherboards likeATX, Micro ATX, Extended ATX, Mini-ATX, and BTX systems. 

The mini-tower, also called a micro tower, is the smallest type of tower case.These cabinets are used for Micro ATX and Flex ATX.

Notebook Cases

The notebooks cases are used for portable computers they resemblance to P.C. {Personal Computer}.

The very small notebook cases are called netbooks or subnotebooks.

Now let us elaborate and discuss more on the topic.

Tower Case

These are versatile cabinets that are equipped with slots to hold drives.

The motherboard is installed in the centre, where all the other components and hardware drives can be easily connected to the motherboard.

They are commonly used in banks and homes.

Full Tower Case

They are huge in size and length. They can incorporate many external drives easily. They are especially used in banks and small offices.

Mini Tower Case

Their height is not huge compared to their counterparts. Due to its small size, not many drives can be attached to them and hence it falls in the category of limited usage.

Slim Case

They are very slim cabinets. They are very slim, therefore, are heavily restricted in use.

SFF Cabinets {Small Form Format} They are very small and compact.

They replaced old cabinets, which used to consume a lot of space. They are also called “Desktop Case”.

10 Parts of the Computer Case With Image | What is Inside the CPU Cabinet?

 Let us discuss what parts and components are attached and installed inside the CPU cabinet.
  • Motherboard.
  • Hard Disk Drive | SSD {Solid State Drive}.
  • RAM {Random Access Memory}.
  • Optical Drives {DVDs}.
  • CPU {Central Processing Unit} | Processor.
  • Cooling Fan
  • Expansion Cards {Graphic Card}.
  • SMPS {Switch Mode Power Supply}.

The motherboard is a sheet of PCB and holds and controls all the electronic components together. The all the circuitry is connected to the motherboard.

The motherboard is the essential part of any computer system responsible for holding or connecting different electronic components like RAM slots, CPU, SATA, PATA slots, expansion slots, bios chips, capacitor, coil, and resistors.

The motherboard is manufactured with a nonconductive material.

The famous motherboard manufacturing companies are Intel, Asus, Gigabyte, MSI, Asrock, Sapphire technology, Biostar, etc.
Hard Disk Drive | SSD {Solid State Drive}.
The computer hard disk drives are known as HDD {Hard Disk Drive} and Fixed disk. They are a type of non-volatile data that is present even after there is a power loss.

They are cheap secondary memory storage devices.

Solid State Drive {SSD}
Solid State Drive {SSD}

They can store data and information permanently, and users and recall the data whenever required.

The hard disk comes in huge storage capacity like 1 T.B. to 4 T.B.

The SSD stands for Solid State Drive. It is based in NAND based flash memory. 

The SSD is also non-volatile memory, and data is not even there is power loss or failure. They are comparatively faster than normal hard disk drives.
