The Top Five Best Micro ATX Cases

Here is a list of top five best Micro ATX cases:

1. Cooler Master MasterBox NR400: The Balance of Compact and Spacious

Leading the list is the Cooler Master MasterBox NR400, a balanced blend of compactness and spaciousness. It stands as an ideal choice for gaming enthusiasts looking for both aesthetics and performance.

Its features include a tempered glass side panel that adds a touch of elegance and allows you to flaunt your PC’s internal components with pride. When it comes to performance, the MasterBox NR400 does not disappoint.

It has provision for multiple fans and radiators, thus ensuring an efficient cooling solution – a critical requirement for gaming PCs. The case features a full mesh front panel and comes with two fans pre-installed.

The removable HDD cage is another great feature, providing extra room to house longer graphics cards. However, one needs to be a bit patient with the cable management due to the compact nature of this case.

2. Cooler Master MasterBox MB320L ARGB: A Fusion of Functionality and Design

Next on the list is the MasterBox MB320L ARGB, another excellent product from Cooler Master. This Micro ATX case integrates functionality with an appealing design.

The dual pre-installed ARGB fans are a delight, adding vibrancy to your gaming rig. Besides, you can control these fans using the motherboard.

The MB320L ARGB supports radiators up to 280mm in the front and a 120mm at the rear, thus offering versatile cooling options. Just like the NR400, this model also features an edge-to-edge transparent side panel to show off your hardware.

Nevertheless, the compact size leaves little room for cable management, which could be a bit tricky for some users.

3. Thermaltake Core V21: The Master of Flexibility and Cooling Efficiency

The Thermaltake Core V21 is a distinctive Micro ATX case, standing out with its unique cube design. This case scores high on flexibility and cooling efficiency.

Its design supports a broad range of cooling and storage solutions. Its most notable feature is its stackability – you can expand your system by stacking other V21 cases.

The case features a pre-installed 200mm front fan with room for more. The multi-orientation layout allows you to place the case either horizontally or vertically. While the shape is unique and functional, it might not align with everyone’s taste or gaming setup.

4. Cooler Master MasterBox Q300L: The Pocket-Friendly Powerhouse

The Cooler Master MasterBox Q300L is an excellent choice for those seeking high functionality at an affordable price. It sports an open design with perforated front, top, and bottom panels for better airflow, vital for maintaining an optimal operating temperature.

The case features a single pre-installed fan with the option to add more if needed. While the Q300L offers excellent features like a transparent side panel, a magnetic dust filter, and an adjustable I/O panel, it can be a bit cramped when accommodating larger components.

5. Thermaltake S100 Snow: The Stylish, Durable, and Quiet

Rounding out our top five is the Thermaltake S100 Snow, a compact, durable, and stylish Micro ATX case. The case comes with a 4mm tempered glass panel, a built-in power supply cover, and a pre-installed 120mm rear fan.

The S100 Snow stands out with its sound-damping panels, keeping your PC’s noise to a minimum. Its sophisticated white exterior gives your gaming setup a sleek, modern touch. The case, however, may not support larger graphic cards due to its compact size.

Each of these Micro ATX cases brings something unique to the table in terms of design, features, and functionality. While some excel in aesthetics, others might offer better cooling solutions or storage capacity.

The ultimate choice boils down to your personal preferences, the specific requirements of your gaming PC, and, of course, your budget.


Choosing the right Micro ATX case involves striking a balance between size, performance, and aesthetics.

The Cooler Master MasterBox NR400, MasterBox MB320L ARGB, Thermaltake Core V21, Cooler Master MasterBox Q300L, and Thermaltake S100 Snow are all fantastic options to consider.

By understanding the features and strengths of each case, you can make a well-informed decision for your next gaming PC build.
