The P180 is truly a revolutionary breakthrough in case design. Dual chambers isolate the power supply and CPU into separate cooling zones with up to 5 configurable fans. Three-layer sound-deadening panels dampen noise even in very high-performance systems. Ease-of-use, sleek design and Antec's reputation for quality make the P180 worthy of being the first Advanced Super Mid Tower. Unique upper and lower chamber structure: The power supply resides in a separate chamber to isolate heat from the system and lower system noise
