Apple's forthcoming mac pro will sport dual Optical Drive slots, if a recent report from AppleInsider pans out. In addition, the power supply is rumored to be moved from the bottom of the enclosure to the top. Otherwise, the enclosure would remain largely unchanged from today's PowerMac G5 design. ThinkSecret currently believes the Mac Pro enclosure change will be a more radical departure from the present design to signify the processor change. Also mentioned in the article is an independent report of possible specifications for the new machines with the "Best" configuration topping out at two 2.66 Ghz Xeon processors. This anonymous source sent possible specs for the Mac Pro to both MacRumors and Appleinsider, and while the validity of the specs are uncertain, the anonymous specs also independently claimed the new Mac Pro would have two optical drives.
