Introduction
The ATX case is defined as a computer chassis that supports the ATX motherboard form factor. The term has been used to define cases for motherboards that are derived from both IBM’s Micro-ATX and Flex-ATX platforms, which are not the same thing as ATX.
Some people use this term like mini-tower and mid-tower. The difference between those is usually the depth of the case and the position of power supply, with micro-ATX cases having bottom-mounted PSU and mid-size ones with top-mounted PSU. There are also differences in motherboard cutouts and external bays.
If you don’t have a dedicated computer case for your motherboard, then you’re going to be limited to some really bad options. You can purchase a small form factor system that comes with a dedicated chassis and power supply, or build your own into a shoebox or something.
People who want an aesthetically pleasing chassis that doesn’t have the same footprint as a standard mid-tower case will often use an ATX case. This is most often seen in home theaters with PCs hidden behind TVs, where space saving is important.
ATX cases are also used by people who want or require high-end hardware that can only be installed into larger computer casings. The small footprint of SFF cases limits you to integrated graphics at best, while [micro-ATX] and [mini-tower] cases have the hardware requirements for powerful gaming systems.
This article will address the characteristics, advantages, and disadvantages of these products. Let’s have a look at some things that you need to consider before buying your Smallest ATX case.
Tips Before Purchasing
Before going to the list of the best Smallest ATX Cases on the market, you should consider some things.
In our list of the [ Smallest ATX cases ], we have considered all these things that a buyer needs to consider before buying a new case. I am not going to repeat them here again, if you want to know more about these things then read this article from top to bottom.
Cable routing:
Many ATX cases have routing holes for cables. If you want to use these holes or if your case doesn’t have them, then you should be prepared to do a little customization.
Also, always keep in mind that you’ll have less room for cable routing in smaller cases, so plan accordingly before building your system.
Support for cooling systems:
Airflow, cooling system, and proper installation of hardware are very important if you want to build a high-end gaming system. In smaller cases, cooling is more difficult to achieve.
If you’re building a high-end system, then your goal should be to get the most out of your components. If you can’t do this in a smaller case, then you should consider getting another chassis rather than limiting yourself to low-end or mid-range hardware.
Tempered glass:
Some cases feature a tempered glass side panel and some do not. This is usually an indication of how expensive the case is.
The reason for this is that tempered glass is very heavy, so the extra weight must be supported by a stronger frame. If you hope to install advanced cooling systems in your ATX case, then tempered glass should be a requirement.
Better outlook:
Many people want to buy ATX cases for their better outlook. They can give your case a unique look if you use them with the right hardware.
Price Range:
ATX cases are generally middle-range products that are more expensive than SFF computers but less expensive than high-end towers. There is a big difference in the price of ATX cases, so you should always consider your budget before buying a new case.

Frequently Asked Questions
What is the smallest ATX case you could possibly find?
Small atx cases are plentiful. Each person has a different selection of PC cases depending on their demands and priorities. The Fractal Design Meshify C is the best case for you if you want a portable computer. It offers outstanding ventilation through its multi-angle front panel.
What is the smallest PC case size feasible?
The smallest PC case is available in three distinct sizes. You may pick according to your workstation and desk space. These cases were designed for this purpose because many individuals desire a portable PC case. The standard ATX measure is 12 x 9.6 inches, whereas the Micro-ATX format is 9.6 x 9.6 inches, and the Mini-ITX format is 6.7 x 6.7 inches (ITX). SilverStone ML08 Slim is a good choice since it has been proven to be the best Mini-ITX enclosure.
Is it possible to fit an ATX case into a MINI ATX system?
Micro-ATX was designed to work in tandem with ATX. Micro-ATX boards have similar mounting holes and I/O panels to those on ATX motherboards. As a result, we inferred that Micro-ATX motherboards could be fitted into full-size ATX enclosures. We suggest you go for the Rosewill Challenger S because it is cheap but still equipped with excellent features.
What is the technical definition of a mini ATX?
The dimensions of a typical Mini-ITX motherboard are 28.4 x 20.8cm. You can install a single-DIN board into a single-DIN space for typical application scenarios such as rack-mount, automobile, tower case, wall-mounted, and so on. If you want greater cable management and flexibility when it comes to air or liquid cooling, we recommend theNZXT H510.
