Mac Pro

Standing 9.9 inches tall and 6.6 inches wide, the Mac Pro occupies about an eighth of the space of the previous model. It's the boldest thing Apple's done in years, not just for aesthetics alone: The silo-esque shape squeezes high-powered components inside the tunnel and cools them efficiently, allowing the compact computer to be as powerful as nearly any full-size desktop.
