Which Computer Case Size Is Best For Your Next Custom PC Build?

When it comes to building a custom PC, deciding on numerous factors could be a tedious job, and computer case size is one of those factors. As in 2022, customers get so many options on the market that might confuse them. But it is somehow a good element because you can get cases that range from expensive and versatile full-tower to refined and elusive mini-tower cases.

Whether you operate your PC as a central component of your home or a significant machine for playing the game, buying the most suitable computer case matters a lot. Now that you want to pick the right case size that meets all your requirements and offers sufficient room for your hardware and USB devices. But some cases are a lot more spacious than deliver adequate innards, muffled sound, fancy tempered glass panels, lower temperatures, RGB lighting, or comprehensive water-cooling support.

But how to find such computer cases?

This article will emphasize extensive guidance for buying the perfect PC case for your computer, first of getting to know about what a PC case is and its purpose.

What is a Computer Case?

A computer case mainly serves as a mode to install and include all the components inside the computer. These components include a hard drive, motherboard, floppy disk drive, optical drive, etc. most of the computer cases are usually made of metal, aluminum, or plastic materials and contain pretty sharp metal edges.

Just like a motherboard, the computer cases also come in various sizes, which are called form factors. The size of these cases must be compatible with the size of the motherboard and power supplies in order to work correctly. Therefore, picking the right computer case size is vital to build a custom PC. There are some best motherboard for rtx 3090 which you can consider buying.

Computer Case Size Variants

A computer case varies from bug to small, which depends on its size and compatibility with other PC components. However, below are the different sizes of a PC case.

Full Towers – Large Cases

Gone are the days when motherboards used to come in a standard ATX form, today motherboards come with a larger power supply, more fans to prevent overheating, custom liquid cooling tubes, dual GPUs, and other excellent add-ons. These additional features directly impact the motherboards’ size and ultimately increase their form factors and come in bulkier motherboards known as E-ATX boards. Generally, full tower cases are significantly larger than the mid-towers and mini-towers, but they are big enough to fit one whole system.

Mid Towers – Standard Cases

These are the most common types of computer cases that most people have. If you’ve been into the gaming PC or work in the office with the computer, you probably have an ATX mid-tower case installed. These cases are capable of fitting most of the motherboards either by AMD or Intel and also allow you to upgrade them for incorporating heavy GPUs or custom cooling systems.

Mini Towers – Small Cases

As its name depicts, the mini-towers are incredibly made to fit smaller motherboards in it and offer two mini-cases, micro-ATX and mini-ITX cases, which are least compared to desktop PCs.

Amongst these two form factors, the mini-ATX is far more common because of its compact building structure and size. The mini-ITX cases require only specific components to function properly, but they are preferable to build and run tiny computers such as laptops or some low-profile desktops.

On the other hand, the micro-ATX form factors have the capability to handle a bit larger motherboards such as the micro-ATX boards. These cases are basically more significant than the mini-ITX but still pretty smaller than the standard ATX forms. These cases are notably different from mid or full towers with respect to different proportions. Yet, these cases are only specified for smaller PCs to save space.

SFF Towers – Smaller Cases

Finally comes the smaller form factor cases, which offer limited features. However, this is one of the incredible options today in terms of portability and building personal computers. This is the perfect fit for various tiny components to make them special LAN cases or HTPCs. Its compact size can fit in all sorts of environments and deliver a flawless flow as per your requirements. You can carry it very conveniently and travel wherever you want. The SFF towers are explicitly developed and have tiny motherboards.

Below, I have given a comparison table to make you more explicit about the form factors and dimensions of the three computer cases.

Conclusive Thoughts

Now that you have looked through the four form factors of a computer case, about their purpose, and the dimensions. So which one should you opt for?

A full tower computer case should be the go-to option because it can hold full form factor motherboards. These cases offer ultimate airflow, water cooling and allow you to upgrade them.

On the other hand, if you’re looking for a well-rounded PC case, you should pick a mini-tower computer case. This case can probably fit all motherboard forms in it other than the larger form factor such as E-ATX. This versatile motherboard not only has the capability to integrate larger components, but they don’t leave you with ample spaces when it comes to cable routing.

For those smaller options, go either mini-towers or SFF towers. A mini-tower could be an excellent option for you if you prefer portability and have been striving for space in your home or office. Consider any of the two options by identifying the space and portability factors.

I hope it has become easier for you to decide which computer case size is perfect for your custom PC build. The suggestions above might help you decide on the most suitable form factor according to your needs.
