"Lancool Metal Boned K7 Case has an aluminum outside, but a steel body. This is an excellent combination because the aluminum reduces weight & looks fantastic, while the steel body ensures strength. It has 3x120mm fans,1x3.5" drive bay and 3x5.25" drive bays, 5 HDD bay cage, removable motherboard tray, cable management system and more. This case is an example of what to look for in a mid-tower case. Watch the video to find out more and check out the bloopers at the end."
