How we picked the best PC cases

We focus on cases that offer a balance of excellent airflow, water-cooling capabilities, and features conducive to gaming setups. We look for cases that are consistently praised for their build quality, ease of assembly, and efficient cooling setups.
In addition to user reviews, we consult publicly available benchmarks and expert opinions to understand the cooling efficiency and build quality of these cases. Factors like air and water cooling support, noise levels, dust filtration, and cable management are scrutinized

Features and Considerations

Good airflow ensures that cool air can enter and hot air can exit efficiently, preventing heat buildup that can affect component performance. Cases with well-designed fan placements, mesh fronts, and ample ventilation are ideal for airflow. For those interested in water cooling, cases that support multiple radiator sizes and have space for pumps and reservoirs are critical.

PC cases come in various sizes like ATX, micro-ATX, and mini-ITX, each catering to different motherboard sizes and component configurations. It’s important to ensure that the case you choose can accommodate your motherboard, GPU, and other components, as well as leave enough room for cable management and air circulation. Find out more on all of this lower down, and also check out our guides for the best Corsair PC case, as well as our best PC case for cable management round-up.

How to pick the best PC case for your needs

In many ways, the case is the backbone of your PC build so picking the best gaming PC case for you is important. While there is a lot to consider– more than we can reasonably talk about here– we’ve gathered the most important factors to look at when shopping for a new case. After all, what starts as the top PC case on your list, might best computer case.

Case Type, motherboard compatibility, and you

After you’ve selected a CPU (often the first part of a PC build), you’ll need to get a compatible motherboard. And when you do, you’ll need a case that is big enough to fit, and which has the proper mounting support for, the motherboard you choose.

There are a number of different case sizes out there that are uniform so that consumers know what cases can use what types of motherboards and how large that case is, etc. However, while there are some popular types of cases, there isn’t a single set of industry standards.

The most popular cases are ATX mid-tower and ATX full-tower with some smaller sizes also being popular, like the mini-ITX or the Small Form Factor ITX (SFF ITX). There are also less common types, like uper towers (larger than full towers).

Small form factor cases usually fit mITX or ITX motherboards. These small motherboards have fewer RAM and PCIe slots. This limits them to usually one graphics card meaning that small form factor cases that use these kinds of motherboards might not be ideal for workstation builds that might need tons of RAM or multiple GPUs.

ATX is more or less the standard when it comes to motherboard layouts and has ample RAM and expansion card space for most builds. eATX is a non-standardized motherboard size and the exact dimensions and specs vary from board to board so be sure to cross-check your case with your motherboard when buying these. However, these are only for the most hardcore builds, so you’ve been warned. Both ATX and sometimes even eATX will fit into mid-tower cases, while any motherboard will fit into a full tower or “super tower” case.

Drive Bays

Drive bays determine how many drives your build can potentially have, and therefore how much storage your rig will be capable of. Typically there are three sizes of drive bays:

  • 2.5-inch bays are for SSDs (solid state drives)
  • 3.5-inch bays are for HDDs (traditional hard drives)
  • 5.25-inch bays are for CD/DVD drives; they are nearly extinct in modernity


Arguably the most important thing to address when picking a PC case is cooling. While this is hard to quantify, there are a few things you can look at when looking at how well a given case will be able to cool your hardware.

For one, how open the case is can determine how well your PC parts will be able to breathe. Cases like the Thermaltake P7 or the Cougar Conquer will offer exceptional airflow and will allow all the components on your motherboard to get fresh air.

The number of fans a given case can accommodate will also affect cooling. Some cases like the Obsidian 1000D can hold an insane amount of fans, which in turn will push tons of air through the case to help keep everything operating at a good temperature.

If you plan to water cool your rig, then making sure you pick a good case for water cooling is essential. Most cases these days have specially designed mounting points for water cooling equipment, but can often only hold radiators of a particular size. Also, some cases can only fit AIO water coolers and do not have the internal space needed for the reservoir and pump of a custom water cooling setup.

Front I/O (In/Out)

The last thing to pay close attention to is the front I/O. These are the different inputs and outputs that are present on the front of the case. All of the cases on this list, and most computer cases in general, have headphone and microphone jacks on the front.

In addition to this, you’ll want to look at what kind of USB ports and how many there are on the case. Some cases only have two USB 2.0 ports on the front. For some, this is enough, while for others a more modern front I/O is demanded.

If you’re looking for the best I/O possible, then make sure you have USB type C and USB 3.0 ports on your case, as these are faster and far more up-to-date than USB 2.0 ports. Crucial for the best PC cases.

Do cases matter for PC?

Yes, cases do matter for PCs. A good case not only defines the aesthetic of your PC but also plays a crucial role in cooling efficiency, component compatibility, and overall system longevity. Factors like airflow, space for components, and build quality can significantly impact the performance and durability of your PC.

Is it OK to let the PC case open?

While leaving a PC case open might seem like a good idea for cooling, it’s generally not recommended. An open case exposes the components to dust, pet hair, and other environmental factors that can harm the hardware. It also disrupts the designed airflow pattern, which can lead to inefficient cooling.
