With its small size and side handle, this case is perfect for LAN gamers; however, it weighs 18 lbs, which is a bit heavier than other lightest cases available on the market. Unlike any other case on the market, this one has a cube shape.

Best Small ATX CaseAlthough Fractal Design is not that well-known, it has gained a good reputation among its customers by providing quality products at an affordable price. Meshify C is the line of casings available from Meshify, and it comes in different colors and sizes. There is no side tempered glass on Meshify C. Despite the lack of tempered glass, the design won’t make your PC look fancy. Innovation is also straightforward. Despite their cheapness, Fractal Design shocked the industry by producing these lightweight cases.

With its full-tower design, the Fractal Design Meshify C supports motherboards with ATX, Micro-ATX, and Mini-ITX standards. This device is designed to accommodate seven fans, 3 on the front panel, 3 on top, and 1 on the rear. In addition to the pre-installed fans, there are two additional fans located on the back of the case. Three 2.5-inch and two 3.5-inch hard drives are supported. Most common graphics cards and CPU coolers are fully compatible with this motherboard, as are many CPU coolers.

There is a lot of space inside this case, which allows air to flow freely through the component to keep it cool. This case is suitable for ATX motherboards. A downside of this case is that it is large enough but cannot accommodate large enthusiast-sized motherboards. It might be necessary to remove the bay drives cage if you have to install three fan radiators. Furthermore, the tempered glass version costs a few dollars more but lacks its side tempered glass.

The bottom line is this case comes with great features at an affordable price, so it has everything you are looking for. This Best Smallest ATX Case, in my opinion, is an ideal option for any budget or mid-range build, but keep in mind that tempered glass is not included.

There are three color schemes available for the NZXT H510 CA-H510B-B1. Since these color schemes match most of the latest motherboards, you can select the one that matches your preferences. As one of the company’s most popular lineups, this case provides excellent thermal and acoustic performance.

With better cable management, the case provides compatibility with ATX motherboards. Throughout this case’s body, you will find matte black color with steel on the right side as well as tempered glass on the left side. Besides the two fans on the front panel, it also has one fan at the top and one at the rear. The front panel also includes two Aer F120mm fans. You can add water cooling systems and custom loops if you are highly obsessed with overclocking and temperatures.

Early NZXT cases limit the amount of airflow in the case, as I mentioned above. In the case of metal fronts and glass sides, airflow may be restricted, but using static pressure fans on the front of the unit will help ensure that the best airflow is achieved. In the case of mounting a 140mm fan on top of the Motherboard, you might block the 8-pin connector. There are also outdated mounting screws for the GPU in this Best Smallest ATX Case.

This case will appeal to anyone who likes aesthetics and RGB, but the airflow isn’t the best. This case will be more than sufficient if it is made of mesh, since the metal front panel hurts.

Also, there is a proximity sensor that illuminates the USB ports in the dark so that USB cables can be attached in the dark, but the sensor is too sensitive. Unlike other chassis, this casing’s rear side lacks a PSU remote switch and mounting space for a rear fan. A total of seven expansion slots are horizontally arranged and two are vertically arranged. As a smaller form factor computer, it’s the best choice, but not for LAN gamers. Other options are available if you want fancy hardware. You can use it at home, at work, or for gaming.

Buying Guide of Best Smallest ATX Cases

Form Factors: 

In addition to the case’s size, we also need to consider the motherboard form factor. Basically, there are four types of ATX: Extended ATX, ATX, Micro ATX, and Mini-ITX. You should pay attention to the form factor. If you are buying or planning on buying a case, make sure that the motherboard will fit inside. If you want to find out which motherboard form factor the chance supports, check the spec sheet.

Quality of the case build: 

The quality of the case you buy for your PC is undoubtedly the most important factor to consider. PC cases made of low-quality materials will have dents and scratches all over, not to mention thin plates, and will become worn out very quickly. High-quality ones have thicker and more shiny frames that are completely free of bends and dents. Low-quality cases may be appealing, but not all that glitters is gold, so choose your PC case wisely.

Management of cable: 

Computer wires should be neat and not cluttered. Organizing them will prevent them from being snarled together. The appearance of a PC might be affected by less organized cables, but they don’t affect performance. To make sure your PC is organized, you need a good case. Because this guide is about the Best Smallest ATX Cases, you should keep this option in mind.

Airflow And CPU Cooling: 

The PC already has a cooler inside it to prevent overheating, but the case you chose will severely reduce its performance. Keeping the air flowing and the CPU cool is crucial. Installing coolers is a must. Which cooler suits your PC depends on your case. Choose a PC case with panels and the capability of accommodating multiple fans. In some cases, liquid cooling radiators and CPU coolers will not fit.

Frequently Asked Questions

What are the different types of ATX Motherboards?

The ATX motherboard comes in four different types with different sizes and configurations. All four kinds of ATX motherboards are available: ATX, also known as Advanced Technology eXtended, (E-ATX), also called Extended ATX, Micro ATX, and Mini ITX. It is possible to use ATX, MATX, and ITX cases, but not the EATX case as it is quite large. In terms of reliability and decent performance, ATX is a good alternative for a compact PC build with an equivalent case size to support the rated components. Widest extended ATX format (12 x 10.7) with 305 * 272mm diameter. In Diameter) ATX width: (12 * 9.5) Under 305 * 244 mm in diameter (Most Popular) Micro ATX: (9.6 * 9.5) Under 244 * 244 mm in diameter (Ideal for Small Builds) Mini ITX width: (6.7 x 6.7) Under 170 x 170 mm in diameter (Most Compact)

What are the advantages of ATX over Micro ATX?

ATX motherboards have many advantages over Micro ATX motherboards, such as greater PCI and RAM, which allows multiple GPUs to be installed simultaneously, creating a powerful portable workstation. Fill every RAM slot with high-speed memory sticks and populate expansions using the given PCI expansion for high-end Graphics Cards. Micro ATX, on the other hand, has a fair amount of evaluation and therefore it offers an excellent value. Compared to other compact rigs, it can support half the RAM slots and GPU mounts. Thus, micro ATX uses less RAM and space than ATX, but can still game like ATX.

What is the best smallest ATX case?

At the top of this list are Lian Li’s O11D Mini and Riotoro’s CR1080. Both are fully customizable to meet your individual needs. These days, people prefer compact to bulky gaming rigs for a number of reasons. Despite having a smaller footprint, ATX cases are able to accommodate liquid coolers, close loops coolers, as well as multiple radiators due to technological advancements. Although ATX cases are compact in size, they provide the ultimate gaming experience when coupled with full-size ATX or MATX gaming motherboards.

How small is the smallest PC case?

PC cases can be built down to sizes as small as 394mm x 245mm x 359mm (D) x 269.5mm x 394mm (W) x 269.5mm (H). For example, such a small PC case can accommodate an ATX motherboard of 12″ x 9.6″ while easily adapting to micro ATX of 9″ x 9″, and the smallest mini-ITX of 6.7″ x 6.7″.

Are micro ATX motherboards compatible with mid-tower cases?

Micro ATX motherboards are easily compatible with mid-tower cases. ATX mid-tower cases typically house standard ATX motherboards, though users can still install micro ATX motherboards. Depending on the understanding, an ATX PC case can house either an ATX motherboard or a mini ITX or micro ATX motherboard. There is only a difference when it comes to upgrades and components fitting with an equivalent motherboard. However, know that the motherboards for ITX are limited in scope and only provide access to relevant components.
