This innovative design decreases TCO (Total Cost of Ownership) by:

1. Increasing the useful life of this PC by keeping the dust & fur out.  When the cooling surfaces of your internal components are clogged with fur or dust, they cannot provide adequate cooling for the unit.  When exposed to prolonged periods of above normal heat, the components will fail prematurely. 
2. Decreasing the labor involved in keeping the inside of the PC case clean.  Three (3) integrated dust-filters trap the fur and dust on the outside of the case, making it quick and easy to clean.  The Dust-Free PC™ greatly reduces the number of times you need to shut-down the PC to clean the inside.  Conventional PC cases need to be cleaned at the beginning and end of shedding season.
