LoopRumors believes that Apple is staging a redesign of its Mac Pro systems. The new systems are said to be smaller, with a new cooling system that will direct hot air out the top of the system rather than the back.

When Apple introduced the Mac Pro in August last year, it left the design of its pro system largely untouched outside of slight internal shifts and the addition of a second optical drive. The Mac Pro was first rumored to be updated last year, with reports that Apple's research and development efforts having been completed some time ago, however the Mac Pro remains unchanged since its introduction.
