Micro ATX Cases – The Buyer’s Guide

We understand that choosing the best micro ATX case can be a difficult venture especially considering how the market is flooded with choices that can scare anyone.

With so many features and specifications available, it can be hard to decide what works best for you and which one will be able to enhance the performance of your system.

It is difficult to find the answers to these questions when you directly look at a list of products. So before you decide to you pick one product from the above-mentioned list, let’s talk about what features you should consider for finding the perfect case that will work for you.

Here are some of the factors you should keep in mind while looking for the best micro ATX case for your system.

1. Design & Customization

One of the first things anybody thinks of is obviously the design. The micro ATX cases come with aesthetics that can make anyone want to grab the product right away. Who doesn’t want a rig that has a tempered glass side panel that looks edgy and cool? But do remember that it means you will have to put in extra work hiding away cables and ugly parts. Do not get fooled into buying a tempered glass case if you are lazy.

The RGB lighting is another attractive feature, especially for gamers. You can customize the lights to match your mood and it looks super pretty in the dark. However, some people may find it irritating, so pick the option that suits your personality.

The market is deluged with cases that offer endless customization. Whether it is changing the position of the I/O front panel or using the case itself in a horizontal or vertical position, you can be sure you find something that fits your needs.

2. Cooling options

If you plan on using liquid coolers or installing custom liquid cooling rigs that come with certain CPUs and GPUs, it is necessary that you pick a case that has adequate openings to install and clean these systems easily. You should also keep in mind that some cases cannot accommodate liquid cooling systems of all sizes.

If you already have a cooling system, you should check if the case you are planning to buy can accommodate the size. Usually, every case has specifications that will indicate the radiator size that it can support so it should be easy to find one that meets your needs.

Having vents at the sides of the case itself can also help reduce overheating and increase the cooling efficiency of the system.

3. Noise

Optimum airflow is essential for running powerful hardware in a system and that can be achieved only by installing fans. However, sometimes installing 3 or more fans can increase the noise factor of the case.

Do not sacrifice airflow for noise reduction because overheating of PC components can cause thermal throttling of the hardware. You can choose to buy a case that comes with noise filters and liners that reduce excessive sound distribution.

4. Dust filter

For those of you who work in a dusty environment, it can be essential to find a case that prevents the entry of dust into the system components. Cases generally tend to gather dust easily, and buildup of dust can definitely affect performance.

Before purchasing a case, make sure that it has effective dust filters which not only prevent the entry but can also be easily accessed. Make sure you can remove them and clean them regularly so that they do not get clogged up.

Some cases also come with magnetic dust panels which further prevent buildup inside the case. Positive airflow can also ensure that your system does not get affected easily.

5. Space for components

Always make sure that the case has enough space to handle all the pieces of equipment you want to install in it. It is a good idea to make a list of all the products you want to install inside, and cross-check the list with the specifications of your desired product.

Depending on the number of drive bays you want, expansion slots, radiators, coolers, and even the type of motherboard you are going to use, the type of case you need to pick may vary vastly. While picking a case, also make sure that it supports not just the number drive bays you want, but also conforms to their sizes.

Motherboard trays inside these cases can also come in a variety of sizes and orientations. You can choose to install your motherboard horizontally and vertically, so make sure you remember to keep that in mind while buying the case.

Having enough space for all the components is not enough, you should also be able to access all these components even after installation. This is especially important when considering fan mounts. It should not only have enough space for installing fans of 80 to 120 mm size, but also enough clearance from other devices and accessibility to them after all the components have been placed inside.

Another important factor to consider is cable management. Some cases are not optimized for handling the cables of all the installed components without appearing messy and ugly. Make sure that the case you buy has enough space for cable management.

Dedicated sections for securing cables and a black plate that can be removed are good indications that the case has good cable management. This will make space look neat and easy to manage. It will also enhance the modification process even after installation.

PSU shrouds are an important factor that is often forgotten. They help in cases where you need to hide loose cables. The shrouds will keep them in a neat enclosure, which is important for cases that have tempered glass side panels.

Graphics cards are becoming shorter and shorter, but you should make sure that the case has enough space to fit in your desired card length. Case specifications will mention the maximum GPU allowance, and it is necessary to match it with the one you have.

You should also match the radiator and cooler size with the specs of the case. CPU coolers, especially, can be quite bulky. When deciding on the case and cooler, check the clearance they need. One thing to keep in mind is that you should match cooler height with the width of the case, as coolers are usually installed horizontally.

6. Durability

The material of the case is one of the most important factors to be considered. The durability of the material is what decides how long it is going to last.

It is essential that you pick a case that comes with the right combination of sturdy and fragile parts. Some components may require the case material to be sturdy enough to support their weight without crumbling under it, while others may require a soft landing pad to prevent accidental damage.

The case should be sturdy enough to not transfer shock or motion to the components. The durability of the case may vary from model to model. It is ideal to spend on a case made of metal or polymer instead of investing in a cheaply made product.

7. Budget

One of the most important factors when buying anything is the budget, obviously. It is essential that you remember what your upper limit is while picking the right product for you. Do not get mesmerized by unnecessary features and blow your budget. Marketing may mesmerize you into buying something that you do not require at all. Just stick with a case that works best for you and fits within your budget.

Having said that, it is also important to not cut back on the quality of the product while trying to save money. Case durability and how well it functions with the specifications of other components of your PC is important because otherwise, you might end up spending more money replacing a low quality or inferior case.

Ultimately the goal is to strike the right balance between finding a durable and flexible case that meets your requirements and also falls within your budget.

Micro ATX Cases – FAQs

1. What is ATX and what is it used for?

ATX Is short for “Advanced Technology eXtended”. It is a specification that outlines the configuration and dimensions of motherboards and improves standardization.

An ATX motherboard has several advantages over other types. For example, they include advanced control facilities including checking the CPU temperature and voltages. As a result, the PC automatically shuts down if overheating occurs.

These motherboards also have a stacked I/O connector panel mounted. With these devices you can easily relocate memory, thus allowing for better ventilation and installation of the key components.

Power management is also easier with the BIOS program. The PC can be turned on by using a modem or network signal because the main power supply is controlled by the motherboard.

Additionally, the PC cannot be turned off while it is booting. If the computer freezes as it is turning on, you can simply turn it off by holding the power button for 5 seconds.

It is also impossible to place the power supply connectors in improperly because the ATX 2.01 Motherboards have a single keyed Molex internal power supply.

2. What is a micro ATX case?

Micro ATX, Mini ATX, and standard ATX motherboards are generally different when it comes to their dimensions. Here are the sizes for each of them:

  • Standard ATX: 12.0″ x 9.6″
  • Micro-ATX: 9.6″ x 9.6″
  • Mini-ITX: 6.7″ x 6.7″

A micro ATX case, therefore, can fit in micro ATX motherboard as well as a mini ITX motherboard, as the latter is shorter in both height and width than the former. However, these cases cannot fit in standard ATX motherboards because the latter is usually longer than the former.

3. How big is a micro ATX case?

A standard ATX motherboard measures 12 by 9.6 inches, and a micro ATX one measures 9.6 x 9.6 inches. A case that supports micro and mini ATX will generally be smaller than one that supports a standard motherboard.

It is also worth noting that a large case may support smaller boards, but it is not necessarily true. It is worth checking the specs of the case to know exact dimensions and specifications to see if it supports the motherboard you want to install in it.

4. Is micro ATX worth it?

Micro ATX motherboards are the best choice. One should go for a standard ATX only if they require more than 4 PCIe slots. Mini ATX boards are good for those of you who want an extremely compact PC.

“Micro ATX boards measure 9.6 by 9.6 inches, and mini ITX ones measure 6.7 by 6.7 inches.”

Besides the size difference, micro ATX can support up to four RAM modules, but mini ones can only support to. For individuals who are committed to gaming, a larger motherboard may be required.

Other differences to be considered are the number of PCIe slots, which are only four in micro ATX. These slots are used by expansion cards like sound cards, internal modems, and graphics cards.

Depending on the type of PC you are planning to build, the RAM you require, and PCIe slots needed, you should pick the motherboard that best fits your needs.

For gamers, we would advise sticking to micro ATX boards as they offer enough RAM and support enough PCIe slots to set up an ideal rig.

5. What is the smallest ATX case?

Here are the best smallest ATX cases in the market.

6. Which is smaller Micro ATX or Mini ATX?

Mini ATX dimensions are 6.7″ x 6.7″ and micro ATX motherboard dimensions are 9.6″ x 9.6″. Therefore, mini ATX is smaller.

7. Can a micro ATX fit in a Mid-tower?

Full tower and mid-tower cases are generally used to fit standard ATX motherboards, but they can also fit in smaller micro ATX motherboards.

Although sizing varies from model to model, most mid-tower cases are 18 inches in height and 8 inches in width, so they can easily make room for a micro ATX motherboard, while still ensuring enough room to fit coolers, graphics cards and storage drives.

8. What is the ATX 12v for?

Over the last few years, ATX Technology has undergone several changes to deal with modern development in power. For the last few years the new format of ATX, called v2.0 or 12V is being used.

This model has a 24 pin main power connector over the previous 20 pin connector and it also does not require a 6 pin AUX power connector. Serial ATA power connectors are a must in this version, and it also shows minimum power wastage in conversion, and thus, higher efficiency.

The most notable change in the modern version of ATX is an addition of 4 pins which ensure additional power can be transferred through the rails.

One of the major advantages of this version is a decrease in wastage of power. When current is pulled from the wall outlet there is the conversion of power from high to low, on the level at which the PC requires it. But even though less power is used, there is extreme wastage in the transfer in the form of heat.

This new version of ATX ensures that less power is pulled from the wall outlet. Minimum efficiency rating with these versions is 80%, but higher ratings can be found in the market.

9. Is my motherboard ATX?

The technology was first released by Intel in 1995, and it is now one of the most commonly used form factor for motherboards. If you have a desktop computer, you most likely have an ATX motherboard.

Here is how to find out the form factor without opening up your computer. Windows users can type ‘cmd’ in the search menu. When the window opens, enter the following command:

wmic baseboard get product, Manufacturer, version, serialnumber, Model, Name. After that, press enter.

The window will reveal the following specs:

  • Manufacturer: the motherboard manufacturer.
  • Name: Base Board or motherboard.
  • Product: the motherboard product name.
  • Serial Number: of the motherboard.
  • Version: of the motherboard.

After that, you can search for the form factor online by using the information above. You only need to know the manufacturer and product name.

Search for manufacturer and product, and it will reveal the form factor.

10. Does the motherboard affect gaming?

Yes, the motherboard does affect gaming, because it features the most important parts of your computer, such as graphics cards and CPU. The motherboard is needed for a computer to be functional so if it dies you cannot use the computer until it is fixed.

It is essential that you keep in mind the hardware you plan to use while purchasing the motherboard. For example, you should keep in mind the number of PCIe slots you will need for video cards, drive bays you may require for memory and USB ports that are needed for connecting peripherals.

Many games require very heavy duty memory so make sure you find a motherboard that stands up to the rigorous requirements.
