The MPX modules look really interesting from a GPU perspective, but I wonder whether Apple will utilize them for anything else in the future (or license the tech - if necessary - to 3rd party vendors)? Specifically, the new tower feels lacking by way of internal storage, but a module that could hold 2-3 traditional 3.5" HDDs would open up a significant possibility for huge capacities. Or some variant of PCIe cards for crazy fast additional storage. There must be dozens of other uses that simply don't occur to me. What do people think?
