What is Cabinet in Computer System With Examples and Diagram

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’s usability.

There are some slots available in the cases that are removable after attaching optical drives to 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 provides voltages to the computer system to function.

The main objective of the SMPS is to convert AC. power to DC. as the computer system operates on the DC. 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, and printer 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 Cabinets in Computer Systems?

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

1. 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.

2. 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 the most used and famous.

These cabinets are used for various motherboards like 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.

3. Notebook Cases

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

The very small notebook cases are called netbooks or subnotebooks.

Now let us elaborate and discuss more on the topic.

4. Tower Case

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

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

They are commonly used in banks and homes.

5. 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.

6. 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.

7. 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 Cases.
