Knowing the Different Types of Computer Cases

A quick online search would tell you that there are plenty of different types of computer cases available on the market. These different types of cases offer their own pros and cons and are also capable of different functions because they come equipped with any number of features.

Knowing the difference between these computer cases will help you in deciding which one will meet your building needs. Continue reading to find out which type of computer chassis will work best for you.

Two Computer Case Classifications

When classified broadly there are only two types of computer cases: the desktop case and the tower case. These classifications have their specific uses, which will help you to identify which of these case types is best suited for you.

Take note that the tower case classification branches out to four other classes that will be discussed later on.

I have included a computer case sizes chart below that details each of the six most prevalent form factors.

The Desktop Model

This type of computer case is considered the most basic of cases. It is what is most commonly seen in homes and offices and offers just the most basic features you'll need in a computer case.

Its main purpose is to keep all the internal components of a computer inside the case to maximize the space provided.

This kind of computer case only works for people who are not planning to expand their computers or those who will only use their computers for its basic uses. This means that builders and gamers will probably find no joy with this type of computer case.


Tower cases are kinds of computer cases that are preferred by builders and gamers. These can be further classified into four: the Small Form Factor, the Mini Tower, the Mid-Tower, and of course the Full Tower.

Here are some pros and cons for each of the tower case types:

Small Form Factor

This type of case is the smallest in the tower case family. It can only support a Mini-ITX motherboard, which means you are very limited in motherboard choices. It is very small and compact, a feature that has its own advantages and disadvantages.

Small means you only have two expansion slots, but it also means it is very portable, making it a preferred tower case for gamers who like to attend LAN parties.

Mini Tower

Since more people want their computers to be portable but at the same time they don't want to sacrifice their expansion capability, the mini tower was created. It can support a Mini-ITX or a MicroATX motherboard and has four expansion slots.

This gives it an edge over the SFF because it is still mobile enough, but not as limited as the latter.


Probably the most common and preferred tower case type is the mid-tower design. It supports the Mini-ITX, MicroATX, and ATX motherboard type and has 7-8 expansion slots, depending on the brand.

This tower also introduces the cable management option, making it a hit with builders who naturally prefer to keep their cases neat and organized. Although it is not as portable as the first two tower types, this is the preferred computer case by many gamers because it can fit high-end graphics cards and still leave room for other expansions.

Full Tower

This is the tower type choice for competitive gamers and server admins all over the world because of its many features and its capacity to hold up to 10 expansion slots. It also supports the four different types of motherboards: Mini-ITX, Micro-ATX, ATX, and the EATX, making it very versatile.

Due to its capacity to store a great number of internal components, a full tower case tends to be very heavy, making it difficult to transport. Although you can push the limits of your computer with this case, you will need to pay attention to its cooling capability because a case this big can easily overheat if the airflow design is not well crafted.

The Perfect Type For You

As it has been mentioned, there is no "perfect" computer case. The best computer case will depend on the builder and what they want and need.

Even if the standard size for most computer cases is the Mid-Tower, this still does not mean it is the best. When deciding which of the types of computer cases you want to purchase, it is best to plan ahead to see how much space and what features you require.

If you have not yet settled on a PC case type, don't worry - keep researching and browsing, you'll find one soon.
