If you have decided to build your own PC, you will know how important it is to select your own components, CPU, motherboard, and GPU are all up there on the list of importance.

You do not need to spend a substantial amount of money on a PC case, however, it must be compatible with the other PC components and motherboard.

We have compared and reviewed five of the best available under $100. We have focused on important specifications such as size, cooling systems, cable management, and motherboard compatibility, to find the best option for you.

Best PC cases under 100: things to consider

Before you purchase a PC case, there are a few different specifications that you will need to take into consideration.

Motherboard Compatibility

The most important factor to consider when choosing a PC case is its compatibility with the motherboard. There are four main types of motherboards – Extended ATX, Standard ATX, Micro-ATX, and Mini-ITX. As these motherboards range in size, the form factor featured on the PC case must match the form factor of the motherboard.

While the size of the PC cases can vary, this does not always determine what motherboard it is compatible with. The best way to determine this is to check the PC description.

The vast majority of cases will state the type of motherboard they are compatible with. While some may be compatible with multiple motherboard types, others are only compatible with one.


The size is important when you take into consideration other components, in particular, the graphics card and core processor.

While the majority of CPUs are of a similar size, the size of GPUs can vary in height and length by a few inches. While this may not seem relevant, it is important that your PC case can hold all of the components you have chosen.

You will need to take its measurements into account and ensure that it is compatible with all of the PC components. In addition to this, if you have smaller components, you will not need to purchase a larger PC case.

Cooling System

The cooling system of your PC case is essential. You will want to ensure that it can dissipate the heat generated successfully. While components will have their own cooling systems, such as fans, vapor chambers, and heatsinks, the PC case needs to be able to dissipate this heat successfully to prevent overheating from occurring.

Ideally, the fans on the case should be placed at the front to help circulate and remove the warmer air the most efficiently. The airflow should be successful, durable, and powerful.

Different PC cases will have different types of cooling systems, but at the minimum, they should have multiple cooling fans and liquid cooling radiators too.

Cable Management System

As all gamers will know, the cable management system is important. Not only is it better for the organization, but it helps to keep your wires safer, untangled, and in a safe place. While this is important outside of the PC, it is important inside the PC case too.

Cable management allows you to keep track of everything within your PC Case with ease. This is particularly useful while building and if you are replacing any of the components in the future.

If the case you have purchased has a glass side, you will want the inside of the PC case to look sleek and aesthetically pleasing. Some cases do help with cable management, which is useful.

There are a few aspects to look for in a PC case with good cable management, such as hooks, loops, holes, and PSU shrouds.


Even if you are building a PC on a budget, the overall cost of the components is an investment, and you will want to ensure that they are suitably protected.

Given this, you will want to choose a PC case that is created by a reliable company and is made from durable materials that are not going to easily dent or damage. This is particularly important if you are looking to purchase a PC case with a glass panel.

The cooling system, cable management, and casing should be wear-resistant and sturdy, you do not want to purchase a flimsy PC case. Even with PC cases under $100, they can still be made from great quality materials to create a solid frame overall.


While the design is not an essential part of choosing a PC case, it is important that you are happy with your choice. After all, the PC case is the shell of the PC and the component that you will see the most.

There are many different types of designs you can purchase, including a wide range of different colors and finishes. In addition to this, many gamers choose to have a glass panel so that they can see the components inside of the PC case.

There is also the option of having RGB lights. These are very popular within the gaming world and allow you to customize and change the color of the lights in your build. They are a great addition and a way to get creative. Even with PC cases under $100, many use RGB lighting.
