The MasterBox MB311L ARGB is a Micro-ATX airflow PC case pre-installed with two ARGB fans and made to be built with the latest gaming hardware
The MasterBox MB311L ARGB is a Micro-ATX airflow PC case pre-installed with two ARGB fans and made to be built with the latest gaming hardware. The front panel’s façade is made entirely of Fine Mesh, placed between two honeycomb vents on either side to maximize airflow. Since running the latest games, smoothly, means keeping the latest hardware efficiently cooled, top panel ventilation offers the option to add even more cooling hardware—if nothing is mounted, the top panel acts as passive ventilation.
The internal layout was engineered for a high compatibility for the latest gaming hardware while also accounting for future upgrades. Following in the principles of the award-winning MB Series, versatility is paired with presentation to ensure that any gaming system built inside the MasterBox MB311L ARGB looks as good as it performs.
FINE MESH FRONT PANEL
Cooler Master’s Fine Mesh design on the front panel is proven to provide proficient airflow while filtering out dust.
MESH INTAKES
Large, mesh intakes span each side of the front panel to provide additional airflow to system.
DUAL ARGB FANS
Two pre-installed 120mm ARGB fans can be managed by the motherboard, and connected by the included splitter, to create a comprehensive ARGB lighting system.
OPTIMIZED AIRFLOW
Airflow is optimized by a collaboration between the Fine Mesh front panel, additional mesh intakes, top panel ventilation, and rear exhaust.
TEMPERED GLASS SIDE PANEL
Hardware, custom-loop cooling, and the pure pride of the builder is shown in panoramic view through an edge-to-edge tempered glass side panel.
ADAPTABLE DRIVE CAGE
The drive cage is able to shift toward the front to accommodate for PSU space, backwards to provide additional radiator space, or even completely removed.
ARGB CONTROLLER
The small ARGB Controller is a mini-sized controller that allows your Addressable RGB such as fans and LED strips to be powered and controlled even in PC systems without an A-RGB capable motherboard.
The controller comes with 14 lighting presets to make full use of the Addressable LEDs in the system and also allows to be completely switched off by long pressing its button.
It is also possible to attach any external 2pin button to it to be able to switch presets without having to open the system. For ease of use, Cooler Master allows the RESET button to be optionally connected to the controller and used as an external ARGB preset switch button.

Designed by Cooler Master, the MasterBox MB311L ARGB is not just any Micro-ATX case; it’s the pinnacle of high airflow performance, with aesthetics to match. This PC case comes pre-installed with dual ARGB fans and is crafted to house the latest gaming hardware. Whether you are a gaming enthusiast or a professional content creator, the MasterBox MB311L ARGB is engineered to provide excellent airflow, expandability, and unparalleled customization options.
The MasterBox MB311L ARGB features Cooler Master’s signature Fine Mesh front panel. This design is not just visually appealing but also serves a critical functional purpose. The mesh ensures that maximum airflow is directed into the case while simultaneously filtering out dust particles, keeping your internal components clean and cool. The mesh panel is flanked by two honeycomb vents that further enhance the airflow dynamics, ensuring your high-performance hardware remains efficiently cooled.
In addition to the Fine Mesh front panel, the case includes large mesh intakes that stretch along both sides of the front panel. These are designed to offer additional pathways for air to flow into the system, which is crucial for maintaining optimal temperatures, especially when you're running demanding applications or the latest AAA games.
Pre-installed with two 120mm ARGB fans, the MasterBox MB311L ARGB takes lighting and cooling to the next level. These fans can be synchronized and managed through your motherboard via an included ARGB splitter. The addressable RGB (ARGB) feature allows you to create a unified lighting system that elevates the aesthetic appeal of your setup. With a multitude of colors and lighting modes available, you can personalize your system according to your preferences.
The optimized airflow design in the MasterBox MB311L ARGB is a collaborative effort involving the Fine Mesh front panel, additional mesh intakes, top panel ventilation, and rear exhaust. Combined, these elements ensure that your components receive ample cooling, thereby enhancing overall system performance. The top panel has optional mounting for cooling hardware, and if unused, it acts as a passive ventilation area.
The panoramic tempered glass side panel of the MasterBox MB311L ARGB allows you to showcase your build in all its glory. Whether you have custom-loop cooling, striking internal components, or elaborate cable management, this edge-to-edge glass panel provides a clear view of your masterpiece. It's not just about building a powerful system; it's about building one that looks stunning.
Versatility is another cornerstone of the MasterBox MB311L ARGB. The drive cage is designed to adapt to your needs, whether you need more space for the power supply or additional room for a radiator. The cage can be shifted toward the front to accommodate a larger PSU, moved backward for extra radiator space, or removed altogether for even more flexibility.
The MasterBox MB311L ARGB offers an array of versatile cooling options to cater to your specific requirements. Fan mounts at the top, front, and rear for various fan configurations, support for multiple liquid cooling setups, and adaptability in drive cage positions mean you can create a bespoke cooling solution tailored to your system's needs. You can install up to two 120/140mm fans at the top, up to three 120mm or two 140mm fans at the front, and one 120mm fan at the rear. For liquid cooling, the top supports up to 240mm radiators, while the front and rear accommodate radiators up to 280mm and 120mm, respectively.
Included with the MasterBox MB311L ARGB is a compact ARGB controller that allows you to manage your Addressable RGB setup. This mini-sized controller is ideal for systems without an A-RGB capable motherboard. It comes with 14 preset lighting modes and also has the option to turn the lighting off entirely by long-pressing its button. The controller adds flexibility by allowing you to connect any external 2-pin button, enabling you to change presets without opening your case. Cooler Master also provides the option to use the RESET button as an external ARGB preset switch.
