Building the perfect custom PC can be a daunting task, especially when you consider the sheer number of cases on the market.
With ever-shrinking components and smaller footprints, it’s now simpler than ever to build what once was considered an impossibly small computer. But finding the right ATX case for your build can be extremely challenging.
With that in mind, we have compiled a list of the best ATX cases for small form factor builds in 2023. These are all ATX sized cases, meaning they will fit an ATX power supply and an additional PCI-E card if desired.
Furthermore, they all offer strong airflows and thermal management options to ensure your build stays cool no matter how intense your gaming sessions get.
By considering these factors and more when selecting an ATX case for your system build, you’ll directly benefit from superior cooling performance – helping you to maximize overall efficiency and minimize component maintenance needs inside your PC! So let’s take a look at some of the top contenders.
Factors to consider
When choosing a smallest ATX case for a compact PC build, there are several factors to consider. First and foremost is the size of the case. The whole point of a compact PC build is to save space, so it’s important to choose a case that is small enough to fit in the desired space.
However, it’s also important to ensure that it is still large enough to accommodate all the necessary components, including the motherboard, power supply, graphics card, and storage devices.
Compatibility is another key factor to consider when choosing a smallest ATX case. It’s important to make sure that the case is compatible with the motherboard and other components being used in the build.
This includes checking for the correct form factor, socket type, and other specifications. Choosing a case that is not compatible with the components being used can lead to compatibility issues and a build that doesn’t work properly.
Cooling is another important factor to consider when choosing it. A compact PC build can be more prone to overheating, so it’s important to choose a case that has adequate cooling options.
This can include features such as fans, ventilation, and the ability to install liquid cooling systems. Additionally, it’s important to consider the noise level of the cooling system and choose a case with a quiet cooling system if noise is a concern.
Cable management is another important factor to consider when choosing a smallest ATX case. A compact PC build can quickly become cluttered with cables, which can impact airflow and cooling.
Choosing a case with good cable management options, such as built-in cable routing channels and tie-down points, can help keep the build organized and improve overall performance.
