The new Mac Pro has become the object of desire, but a lustrous finish hides its true beauty - the massive power within. If you're a pro user in the video or audio industries, the Mac Pro offers the power you need, but lacks the built-in expandability you count on. In order to achieve this engineering feat, Apple designers stripped away components and space to a minimum, taking out PCIe slots and drive bays, and packed the remaining components into a small cylinder. Its compact size makes the new Mac Pro more transportable and rackable, but prevents onboard installation of PCIe expansion cards. In addition, the computer still requires an enclosure to make it road- or rack-ready and provide convenient cable management. Sonnet's xMac Pro Server PCIe expansion system/4U rackmount enclosure addresses these issues and increases a Mac Pro's potential in a big way.
