Closer Look Cooler Master Basterbox Q500L »

MasterBox Q500LLast year Cooler Master released one of the coolest cases for their MasterBox series, Q300L. Q300L has Mini-Tower design which supports Micro-ATX and Mini-ITX motherboards. The case was designed with a great concern for mobility, style, and customizability. In short, the release of Q300L was a huge success. This year, Cooler Master just released Q500L case which has the same characteristics as Q300L but with few internal changes. MasterBox Q500L is a Mini-Tower case with Acrylic window that supports Mini-ITX, Micro-ATX and ATX type of motherboards.

The shipping box of MasterBox Q500L is nearly identical to Q300L. This recycle friendly shipping box offers good structural support and also very light in weight. Entire package weight is about 12Lb. Some of the Q500L features are described in black and white on the box.


Overall it is hard to say what color is the case or what kind of window is in this case because of the lack of the color.

Internally the case was packaged in between of two plastic foam inserts which kept actual case snug in the box. The Q500L was covered with a protective plastic bag to help with any accidental scratches. The left side window is made from Acrylic and partially transparent. To keep this part of the case damage free Cooler Master applied thin plastic tape to the outer side of the Acrylic window.

MasterBox Q500L

The Q500L doesn’t have much of accessory pack. What I found in the case was MasterBox Q500L instruction manual, a small bag with miscellaneous screws and a warranty card.
