The Best Micro ATX Cases (2022 Reviews)

6 Best Micro ATX Cases (2023 Reviews)

Everyone loves a huge PC they can deck out with the best components. A larger-sized PC case allows us so much space to work with and has possibilities of endless customizations. However, it is not feasible for many.

Many people simply do not have space for a massive PC, yet they still want something that will pack in as much of a punch as a regular giant PC. 

People often search up ‘pc case micro atx’ and ‘matx vs atx,’ so there is definitely a demand. Due to such a demand comes in the microatx cases. They are designed to have two functions, be small and save space. Of course, the small form factor leaves a lot to be desired, but in terms of saving you space, it does its job, and it does it well. 

It is important to note that if you opt for a Micro ATX case or a Mini atx case, you will have to think. Choosing components for such a case might be a little tricky. If you have the skill, you can end up with a high-end PC with cutting-edge technology that can do whatever you want it to. Additionally, it will be cost-efficient too.

Even though these cases are super cost-efficient and space-efficient, they aren’t extremely popular. There are many reasons for this. 

Firstly, matx case cases tend to heat up faster than others. The reasoning behind this build-up of heat is the components that are essentially pushed very close together. This heat-up may hinder the performance of the PC. Larger cases often feature liquid cooling to allow the insides to cool down, but that is absent in micro ATX cases to save space.

Secondly, micro ATX cases are a challenge to put together. Most people enjoy building their PC from scratch. For this one, you might have to leave it to the professionals. 

Despite the few drawbacks, Micro ATX cases are ingenious. For those who know their way around PCs and are up for the challenge of fitting everything inside this tiny PC case, a micro ATX case is perfect.

What Does Micro-ATX Case Mean?

Micro-ATX cases are computer cases meant to hold a Micro-ATX, also known as mATX, motherboard along with its related components. They are designed to safely and effectively manage the computer’s internal workings safely and effectively by utilizing an integrated power supply, built-in cooling systems, and modular form factors. When combined, these qualities increase the Micro-ATX construction’s ability and establish the groundwork for a high-performance PC.

ATX versus Micro-ATX versus Mini-ITX

What is the difference between different motherboard designs, and when should you utilize which one? Let us first define each term:

ATX motherboard. The Standard ATX also called the Advanced Technology Extended, motherboards measure 12.0″ x 9.6″ and include the most PCIe lanes for demanding graphics-oriented systems.

Micro-ATX motherboard. Micro-ATX motherboards are 9.6″ x 9.6″ in size, offering the ideal blend of high performance and practical sizing.

Mini-ITX motherboard. Mini-ITX motherboards are smaller than ATX and mATX motherboards, measuring only 6.7″ x 6.7″, and are ideal for compact setups and portable systems.

As you can see, Micro-ATX is smack in the middle of the other two big players, providing the optimal balance of power and capability for gaming PCs and everyday setups. And, because Micro-ATX cases are often considered compact form-factor machines, they may fit a lot of new technology into a small tower. Finally, the best Micro-ATX cases assist you in getting the best out of your motherboard to provide unequaled performance and a plethora of excellent benefits.

MATX Motherboard Size

The motherboard form factor is smaller than ATX, MATX, or Mini ATX. It is an excellent choice for customers seeking a more compact system without compromising functionality since, despite its compact size, it’s able to accommodate a full-size CPU socket and numerous expansion slots.

It is 9.6 x 9.6 inches square and is smaller than a conventional micro ATX motherboard. It is also frequently used in low-cost projects due to the fact that it’s quite affordable.


The motherboard form factor, often known as MATX or Mini ATX, determines the size as well as the design of the motherboard in a computer. Even though the system does not directly specify fans, digital fan controllers compatible with MATX motherboards can be used to cool it.

Case and CPU fans are computer builds’ two most common fan types. Case fans are frequently located on the front, rear, or side of the computer case to circulate air throughout the system to keep the elements cool. On the other hand, CPU fans are designed to cool the central processor by extracting heat from it.


The MATX motherboard form factor, sometimes Mini ATX, has zero to do with SMPS devices. On the other hand, SMPS units are essential components of every computer configuration, including those that employ MATX motherboards.

An SMPS unit’s job is to convert alternating current (AC) electricity from an outlet into direct current (DC) power that computer parts may use. The SMPS unit also adjusts voltage and current to guarantee that the computer components receive a continuous and steady power source.

MATX Dimensions

The MATX, or Mini ATX, the motherboard form factor, was developed as a more compact and reasonably priced substitute for the classic ATX form factor. A standard MATX motherboard measuring 9.6 by 9.6 inches (244 by 244 mm) is square in shape. This is significantly smaller compared to the ATX motherboard with dimensions of 12 x 9.6 inches (305 x 244 mm).

Due to their smaller size, MATX motherboards are popular for clients who wish to build more compact machines without losing functionality. MATX motherboards can still accommodate a full-size CPU socket and a number of expansion slots, typically 4 to 5 PCIe slots plus 2 to 4 RAM slots, depending on the model.

MATX Graphic Card Size

The dimensions of the graphics card, which you can use with a MATX motherboard, are determined by the size of the chassis in which it may be installed. Graphics cards measuring up to 12 inches or 305 millimeters in length are normally supported by MATX cases, while some bigger cases may be able to accommodate longer cards.

Because larger graphics cards may restrict other expansion slots on the motherboard, users should ensure that there’s ample room in the case for the card and any other components they intend to install.

Users should also consider the graphics card’s power requirements and ensure the SMPS unit can provide enough power to support them.

What are the Advantages of choosing Micro-ATX Cases?

There are several advantages to using a Micro-ATX case as your primary gaming rig chassis. Consider the following:

Sizing is convenient. Because Micro-ATX motherboards are comparatively smaller than similar gaming boards, allowing you to select from a wide range of modular cases to find the best fit for your rig.

Options for performance. Micro-ATX motherboards are some of the most popular among PC gamers because they’re packed with cutting-edge technology. Of course, the most desirable mATX cases follow suit, with excellent power supply, cooling systems, as well as USB connectivity.

Designs that are appealing. There are numerous variations on the market, ranging from simple single-color designs to impressive LED-backlit tempered glass models. Top PC gaming brands provide thin towers, cube forms, and custom-molded alternatives.

Advantage in gaming. Because they are specifically engineered to perform seamlessly for gamers, you can be confident that you are taking full advantage of the strongest hardware available on the market.

How to Build a Micro-ATX Case

Fortunately, constructing and using some of the best Micro-ATX cases is similar to assembling and using any other type of computer case. While each model is unique, you will receive simple form factors allowing you to add your hardware with a few screws plus a little effort. However, things become more complicated when modular models or mid-tower cases are included.

Things You Need To Consider Before Buying a Micro ATX Case

Wanting a small case can be extremely tempting when you have less space to work with. However, many challenges come with downsizing to a Micro ARX case. 

Before wading into the market and buying a microatx pc case, here are a few things that you should consider before you swipe your card.

1. Customizability and Design

Many people look at the design of their PCs before anything else. This is because that is what you observe from the outside. A tempered glass case might seem extremely tempting, but you should consider the extra work you will have to put in. 

With everything on show, hiding the cables and making them look neat and tidy is difficult. With micro atx cases, there is already less space, so managing cables becomes harder than usual. 

The upside to having a glass case is that it allows you to put in colored LED strips and RGB fans. They make the case look extremely pretty and can brighten up the place.

2. Cooling

Micro ATX cases are designed to be small. So, the chances of it heating up are quite high. Hence, you must choose a Micro ATX case that allows multiple cooling options. If you intend on installing custom cooling rigs, choose a Micro ATX case that allows you the option to both install and clean such systems. 

A proper vent system is also invaluable in helping the components stay cool.

3. Space for Components:

With the desire to use as little space as possible, you might want to go for the smallest case on the market. As tempting as that may be, a small case is not the smartest way to go about things.

When choosing a case, keep the number and size of your components in mind. Ask yourself whether or not your case can handle all of them?
