A Closer Look at the Cooler Master MasterBox 5 (MCX-B5S1-KWNN-11) »

CM MasterBox 5 Windowed Black with MeshFlow Front PanelThe Canadian model for the MasterBox 5 was released initially several weeks ago (and was previously reviewed here at Modders-Inc) but the US version has finally arrived starting with two options for Americans to choose from: one black version and one white. The Cooler Master MasterBox 5 MCX-B5S1-KWNN-11 (black with MeshFlow Front Panel) comes bundled with a pair of 120mm fans, a PSU cover, a 3.5″ drive cage, a 2.5″ drive cage and a windowed side panel while the MasterBox 5 MCX-B5S2-WWNN-01 (white with darkmirror front panel) comes with the same configuration.

Product was given in exchange for work to produce review.

The MasterBox 5 ships in a brown box with black print, a classical approach to packaging as is expected of a case under $100. The foam padding is specifically customized for the MasterBox 5 case with a small cutout at the top for the accessories and manual that are exposed upon opening the top. The case itself is wrapped in a large plastic bag with the warranty information sheet also sitting on top.

You can tell from the box that this is the black version with seamless mesh front because the model number MCX-B5S1-KWNN-11 is printed at the top.
