Micro-ATX Case Guide Part I: What is a Micro-ATX Case?

Micro-ATX cases are a type of computer case designed to house a Micro-ATX, aka mATX, motherboard and its associated components. They’re built to safely and effectively manage the computer’s internal workings through the use of integrated power supplies, built-in cooling systems, and modular form factors. Together, these features enhance the power of the Micro-ATX build and lay the perfect foundation for a performance-oriented PC.

ATX vs Micro-ATX vs Mini-ITX

Micro-ATX sizes

You may be wondering what the difference is between these motherboard designs, and when you should use each option. First, let’s define each term:

  • ATX motherboard. Measuring 12.0” x 9.6”, standard ATX, or Advanced Technology Extended, motherboards feature the largest number of PCIe lanes for intensive graphics-oriented setups.
  • Micro-ATX motherboard. The star of our article, Micro-ATX motherboards are 9.6” x 9.6” and offer the perfect balance between high-performance and convenient sizing.
  • Mini-ITX motherboard. Smaller than both ATX and mATX motherboards, the Mini-ITX measures only 6.7” x 6.7” and is perfect for smaller rigs and portable units.

As you can see, Micro-ATX fits right between the other two major players, offering the ideal amount of power and functionality for gaming PCs and everyday builds. And since Micro-ATX cases are generally considered small form-factor units, they manage to squeeze a lot of exciting tech into one small tower. Ultimately, the best Micro-ATX cases help you make the most of your motherboard to deliver unrivaled performance and a myriad of exceptional benefits.

Micro-ATX Case Guide Part II: Benefits of the Best Micro-ATX Cases

There are a number of benefits to choosing a Micro-ATX case as your main gaming rig chassis. Let’s take a look:

  • Convenient sizing. Since Micro-ATX motherboards are smaller than comparable gaming boards, you can choose from a variety of modular cases to find the perfect fit for your setup.
  • Performance options. Micro-ATX motherboards are among the most popular for PC gamers for a reason: they’re loaded with fantastic tech. Naturally, the best mATX cases follow suit and feature great power supplies, cooling systems, and USB options.
  • Attractive designs. From sleek single-color designs to LED-backlit tempered glass models, there is a huge variety of options on the market. Choose from slim towers, cube shapes, and custom-molded options by the top PC gaming brands.
  • Gaming advantage. Since they’re uniquely designed to perform flawlessly for gamers, you can be sure that you’re pressing the full advantage with the most powerful hardware on the market.

Plus, each case comes with its own set of features that make it stand out from the rest. But that begs the question — how do you pick the best one?


Micro-ATX Case Guide Part III: Choosing the Best Micro-ATX Case

Picking the right Micro-ATX case can be difficult given the number of options available. To make the process easier, let’s look at some of the top specifications found in the best Micro-ATX cases:

  • Versatile motherboard mounts
  • Space for dedicated GPUs
  • Adaptable form factors & sleek designs
  • Air & liquid cooling systems
  • Loaded I/O panels with USB 3.0 & above
  • Built-in cable routing
  • LED illumination options
  • Room for the best Micro-ATX PC components

Base-level cases with no shrills can be found for around $20, but you’re looking at features like simple air cooling, bare-bones form factors, and older USB 2.0 technology. This is all fine for folks who want to spend their moola on the internal hardware itself.

That said, those seeking the very best Micro-ATX case can choose from options like sleek form factors with modular functions, powerful integrated components with loads of bays and expansion slots, and tech like USB 3.1. But, you’ll have to shell out more money. It’s a balancing act, so look over your budget and opt for a model that will make you happy in the long run (and be sure to leave room for future upgrades).

Micro-ATX Case Guide Part IV: How to Setup a Micro-ATX Case

Fortunately, assembling and using one of the best Micro-ATX cases works just like all the best computer cases. While there are key differences between every model, you can generally expect simple form factors that allow you to insert your components with a few screws and a little elbow grease. However, things get trickier when factoring in modular models and mid-tower cases.
