Does A PC Case Matter? Things To Consider

There are many choices for PC cases, and choosing the right one should not be taken lightly. It’s essential to understand the value a good PC case can bring to your setup before investing in one.

PC cases serve a lot more purpose than just aesthetics. Keep reading if you’d like to learn more about them and how to choose the right one for you.

Does A PC Case Matter? 

A PC case matters for your PC’s build and look. Regardless of how many parts you can afford, you will almost always be limited by what the PC case can hold. A good case will also have better ventilation that will protect your PC from overheating.

Your choice of PC case is as important as a decision like GPUs and monitor types. It might not have as much direct impact as other components, but since it houses almost everything that keeps the PC running, it’s best to think carefully before investing in one.

How To Choose A PC Case?

You should choose a PC case based on size, support, and fan space. The form factor of your case affects everything that goes into it, so making the right choice is important. 

To do that, you’ll have to understand the features to look out for when choosing a PC case. Here are a few things to consider when choosing a PC case:


The first choice to make when choosing a PC case is the size. Size is an overall limiting factor and will affect fan placements, GPU number, and various other features. There are many specific types of cases, but the three broad classifications are:

  • Mid-tower: The mid-tower is the most popular case size and is what most home computers are modeled on. Mid-tower is the middle ground between the other two sizes and usually has space for at least two graphics cards and plenty of storage. The exact size varies, but most are usually around 18 inches (45.72 centimeters) long and 8 inches (20.32 centimeters) wide. 
  • Full tower: Full towers are extremely large and rare for home PCs. They usually measure more than 20 inches (50.8 centimeters) in height and hold more equipment than their counterparts. A full tower is particularly good if you need an extensive cooling system, especially if you plan to overclock multiple GPUs in a single case.
  • Mini-ITX: The Mini-ITX is the smallest form factor you can get for your PC. The small size makes them portable but it limits the number of features, usually making them unsuitable for gaming PCs.

Fan Space

Fan space is extremely important when choosing a case. The type of case directly influences the number and placement of fans. It is important to select a case that can hold the number of GPUs and the required cooling to keep them running.

The full tower and mid-tower form factors are the best options for adequate fan space. When shopping for fans, the optimal number is three, which allows you to set up positive air pressure. However, you can get by with just two fans, provided your setup does not get too hot.

With a two-fan setup, you’ll have only one exhaust fan and another for intake. However, a three-fan setup has two intake fans, increasing fresh air and improving circulation for better cooling. 

You can set up even more fans for better cooling with the larger full-tower setup. You’ll need to be careful about your fan placement, though, as having too many fans can set up conflicting air currents.


Let’s be honest, if you are going to splurge on building a gaming PC from scratch, you probably want it to look good, too.

Modern gaming PCs tend to be just as much as about aesthetics as they are about performance. When it comes to the case you choose, you may want to opt for a case with RGB LEDs, LED fans, carbon fiber elements, and glass paneling.

Many cases have a glass panel on one side of the PC case. This allows the internal PC components to be seen from the outside of the case. You’ll especially want glass paneling if you have fancy lights on your CPU cooler or GPU that you want to show off.

Best PC Cases?

Since a big part of PC cases is aesthetics, the best PC case for you will come down to personal preference. In my opinion, the best PC case is the Cooler Master Cosmos C700P. Choosing a PC case is important, so it’s best to do proper research to find the right one for you. 

If you’d rather pick a ready-made case, I’ve got you covered too! Your choice could vary depending on your needs, so here are two options that should cover people on opposing ends of the price line. All devices are available on

Corsair Carbide 275R 

The Corsair Carbide 275R won’t win any awards as the overall best case, but it is one of the best budget cases available. It’s a mid-tower case with a tempered glass side panel to display your PC’s components which is good for aesthetics. It also comes with plenty of space for storage devices.

Cooler Master Cosmos C700P

The Cooler Master is a beast of a case. Standing at just over 25-inches (63.5 centimeters), this full tower case comes with tempered glass sides, liquid cooling, and extended ATX support. Its size also makes it unlikely that you’ll be strapped for space while installing components. 

The main downside is the price. At a hefty price, it costs as much as some gaming laptops, so investing in a case like this is not for everyone.

Do PC Cases Affect Performance?

A PC case affects performance indirectly through airflow. The PC case is not an electrical component and has no direct effect on the computer. However, your case is a major determinant of airflow. Bad airflow increases processor temperatures which causes throttling and reduced performance.

Additionally, the amount and type of components you can put into your PC are limited by the form factor of your case, so larger ones are usually linked to better-performing PCs since there’s more room to upgrade performance.

Is A PC Case Important for Gaming?

Your PC case is important for gaming because it limits what kinds of components you can install. Due to this, it’s important to go with a case that will give you enough room for good ventilation and the type of processors you want to use.

Balancing the type of case you want with the processors, motherboard, and cooling you want is important enough that you’ll want to pay proper attention to your choice. In addition, the case is the main structure protecting the insides of your computer. Without it, your equipment would be exposed to dust, moisture, and other hazards.

Does A Bigger PC Case Mean Better Airflow?

A bigger case usually means better airflow since you have more space to mount fans. As long as your fans are arranged to maximum effect, you’ll get better airflow in a bigger case. That said, having too many fans can cause them to impede each other’s air currents, degrading airflow.

A bigger case does not always give better airflow or performance. While there is more fan space, you might get comparable airflow with a smaller case if it has better management.

Final Thoughts

Your PC case is very important as it protects your computer’s parts from dust and optimizes airflow. For most people, a mid-tower form factor will serve you best, but if you want multiple GPUs and liquid cooling systems, you might need the increased space from a full tower.
