Review: Nice. - It's a nice , entry level builder's model. No real bells and whistles , just very well-thought out. And it has nothing but airflow. The 2 fans that come with it are cheap as all getout , run of an adapter , not a motherboard hander , and don't have a 3 or 4 pin plug , they'll get you into the argb game , but just enough to immediately look for proper replacements. If you're new to this PC building stuff , the case is fantastic with all rolled edges , no weird arcane steps to be functional. And for anybody that ever had the Darkflash DLM-22 , it's about the same size but with one distinction , it does what a good case should do , flow air and look reasonable doing it. If you're on a budget that's slightly less than what this costs , wait a bit and get it when you can , it's worth it. ## Features - Mesh intakes large mesh intakes span each side of the front panel to provide additional airflow to system - Dual ARGB fans 2 pre-installed 120 millimeter ARGB fans can be managed by the motherboard connected by the included splitter to create a comprehensive ARGB lighting system - Tempered glass hardware custom-loop cooling or the pure pride of showing off the build in panoramic view through an edge-to-edge tempered glass side panel - Adaptable drive cage: The drive cage is movable able to shift toward the front to accommodate for PSU space backwards to provide additional radiator space or even completely removed - Versatile cooling options support for a total of 6 120 millimeter fans and front top and rear radiator placement ensures that you don’t have to compromise on performance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0842T2KWZ | | Antenna Location | Business | | Best Sellers Rank | #1,654 in Computer Cases | | Brand | Cooler Master | | Case Type | Tower | | Color | Micro-ATX Tower ARGB | | Compatible Devices | Micro ATX, Mini ITX | | Cooling Method | Fan | | Customer Reviews | 4.6 out of 5 stars 2,793 Reviews | | Enclosure Material | Tempered Glass | | Fan Size | 120 Millimeters | | Global Trade Identification Number | 00884102069604, 00884102069901 | | Hard Disk Form Factor | 3.5 Inches | | Internal Bays Quantity | 4 | | Item Dimensions D x W x H | 17.15"D x 8.56"W x 16.14"H | | Item Weight | 6.3 Kilograms | | Light Color | ARGB | | Manufacturer | Cooler Master | | Material | Tempered Glass | | Mfr Part Number | MCB-B320L-KGNN-S02 | | Model Name | MasterBox MB320L ARGB | | Model Number | MCB-B320L-KGNN-S02 | | Motherboard Compatability | Micro ATX , Mini ITX | | Number of Fans | 2 | | Power Supply Mounting Type | Bottom Mount | | Recommended Uses For Product | Business | | Supported Motherboard | Micro ATX, Mini ITX | | Total Expansion Slots Quantity | 4 | | Total USB 2.0 Ports | 2 | | Total USB 3.0 Ports | 2 | | Total Usb Ports | 3 | | UPC | 884102069604 884102069901 | | Warranty Description | 1 Year | ## Product Details - **Brand:** Cooler Master - **Case Type:** Tower - **Color:** Micro-ATX Tower ARGB - **Cooling Method:** Fan - **Fan Size:** 120 Millimeters - **Material:** Tempered Glass - **Model Name:** MasterBox MB320L ARGB - **Motherboard Compatability:** Micro ATX, Mini ITX - **Power Supply Mounting Type:** Bottom Mount - **Recommended Uses For Product:** Business ## Images ![Cooler Master MasterBox MB320L ARGB Micro-ATX with Dual ARGB Fans, DarkMirror Front Panel, Mesh Front Intake Vents, Tempered Glass Side Panel & ARGB Lighting System - Image 1](https://m.media-amazon.com/images/I/61BFX1QctKL.jpg) ![Cooler Master MasterBox MB320L ARGB Micro-ATX with Dual ARGB Fans, DarkMirror Front Panel, Mesh Front Intake Vents, Tempered Glass Side Panel & ARGB Lighting System - Image 2](https://m.media-amazon.com/images/I/715ijnx7xeL.jpg) ![Cooler Master MasterBox MB320L ARGB Micro-ATX with Dual ARGB Fans, DarkMirror Front Panel, Mesh Front Intake Vents, Tempered Glass Side Panel & ARGB Lighting System - Image 3](https://m.media-amazon.com/images/I/81luUEHImdL.jpg) ![Cooler Master MasterBox MB320L ARGB Micro-ATX with Dual ARGB Fans, DarkMirror Front Panel, Mesh Front Intake Vents, Tempered Glass Side Panel & ARGB Lighting System - Image 4](https://m.media-amazon.com/images/I/81-GZEpBnnL.jpg) ![Cooler Master MasterBox MB320L ARGB Micro-ATX with Dual ARGB Fans, DarkMirror Front Panel, Mesh Front Intake Vents, Tempered Glass Side Panel & ARGB Lighting System - Image 5](https://m.media-amazon.com/images/I/818cpYgAatL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: How to connect the argb fan to asus b450m-plus** A: You would not be able to wire it to a motherboard that does not have an ARGB header. You would have to use the manual controller that is included with the MB311L ARGB case. CM-PNguyen **Q: How can I connect the fans to software to control lights?** A: That is a great question Lisa. The instructions were so bad I couldn't figure out how to connect them so I did a search. A great deal of people have had the same problem. Try contacting Cooler Master. **Q: will the vetroo v5 work with this case?** A: Yes it should work - specs say max height is 148mm and the case says max CPU cooler height in 168mm so you should have enough clearance **Q: Are the fans supposed to spin all the time? My light up but do not spin.** A: They are supposed to spin all the time, if your power is connected properly and it is still not spinning that might not be a good sign. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cooler Master MasterBox MB311L ARGB *by E***E on June 9, 2024* The Cooler Master MasterBox MB311L ARGB Airflow Micro-ATX Tower is a compact yet powerful case that offers impressive airflow and stunning aesthetics.

It hasn't failed on me. Pros: Spacious (This things fits my 6900xt reference just fine) Comes with 2 front case fans that aren't too noisy Easy to take apart (tempered glass, front panel, back panel) RGB (because.. lights) Tempered glass so you can look at your bright shiny things Con Cable management is a pain (could be a "me" thing, but it's pretty tight back there) I bought this case for my first build last year (5600g build) and it hasn't failed yet. Through my nervous reopening and upgrading parts (yeah, I still get nervous opening up my built system), it's still running fine.
