"The Cooler Master Centurion 534 Case is a budget case, but it has lots of features and looks great. There are five 5.25" & one 3.5" external drive bays, as well as four 3.5" internal drive bays. It has a tool-less design on both the drive bays and the expansion slots, making installation and removal a snap. One 120mm fan is included and an optional one can be added. This is not Stacker quality, although if you are looking for an affordable quality product, check it out. Watch the Video to find out more..." ~3dGameMan.com
