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.

For next month German company Compucase has planned the European release of another Cougar-branded PC chassis, the Evolution BO. This 'Super Midi-Tower' is a variation of the already-available Evolution model and features a black/orange color scheme, a steel structure, support for micro ATX and ATX motherboards, and a top-mounted 3.5-inch/2.5-inch SATA drive dock.

The Evolution BO measures 223 (W) x 523 (D) x 514 (H) mm, and has an I/O panel with two USB 2.0 and two USB 3.0 ports, a built-in fan controller, six external 5.25-inch bays (with tool-free mounting systems), four internal 3.5-inch trays, eight PCI slots, one 120 mm Vortex HDB fan installed at the rear (up to six more fans can be installed), and two pre-drilled holes for watercooling tubing (found at the back).

According to its maker, the Evolution BO will hit stores priced at 99 Euro.
