Antec's continually P182, Performance One design. More innovations have been built in, such as an external fan control for the top and rear fans, a special gunmetal black finish, cable organizers and even ports with rubber grommets for externally mounted liquid-cooling radiators. All of these improvements build upon the great features of the original P180: the triple layer side panels and door design, and the upper and lower chamber structure to isolate power supply heat from the rest of your components.
