Apple did not provide any look at the design of its next-generation Mac Pro, but Schiller did make it clear through his statements that it will be a modular system. This means that all the key components of the system should be easily removable and upgradeable — something which is the very essence of a pro system. This also means that the new Mac Pro will sport a design that is not even close to the trash can design of the existing model.
The modular design of the new Mac Pro will make it upgradeable in nature. While it is unclear if Apple will make it user upgradeable, the design will be such that it will easily allow Apple to continue updating it for years to come, unlike the existing Mac Pro. This indirectly also means that the new Mac Pro will feature a bigger chassis which will allow it to have a bigger thermal headroom.
“To do something that can be supported for a long time with customers with updates and upgrades throughout the years. We’ll take the time it takes to do that. The current Mac Pro, as we’ve said a few times, was constrained thermally and it restricted our ability to upgrade it.” – Phil Schiller
