German feline-loving firm Cougar has now rolled out two more Evolution Series full tower PC cases, the Evolution BO (which we mentioned back in January) and the Evolution Galaxy. These models feature similar specs but come with their own color theme - black and orange for the EBO and black and white for the EG. Seen below, Cougar's cases measure 223 (W) x 523 (D) x 514 (H) mm, and have a steel 'skeleton', an I/O panel with two USB 2.0 and two USB 3.0 ports, a top-mounted 3.5-inch/2.5-inch SATA drive dock, a built-in fan controller, six external 5.25-inch bays (with tool-free mounting systems), four internal 3.5-inch trays, and eight PCI slots. The Evolution BO also packs a 120 mm Vortex HDB rear fan. Both the Evolution BO and Evolution Galaxy have a recommended price tag of $94.99.
