The main complaint many people have about the forthcoming Mac Pro is the lack of internal expandability. Post-production professionals have Mac Pros with PCIe cards for important functions, internal storage and disc burners. They’ve invested a lot of money in workflows that require this hardware.
I’ve come up with a product idea that might satisfy many people with this complaint: A PCI Express card that can be installed in an older Mac Pro that uses one or two Thunderbolt 2 cables to connect to a 2013 Mac Pro. This would turn the old Mac Pro into an expansion chassis for the new Mac Pro.
This solution would provide access to the other PCI Express cards in the old Mac plus internal storage and disc burners (by connecting internal cables to the card if access via the PCI bus is a problem).
Such a card is easier to engineer than a whole expansion chassis. The old Mac Pro provides everything needed but the interface.
You could even attach more than one old Mac Pro to a 2013 Mac Pro using this method…
A valid idea for Kickstarter? The pro][pro card for your new Mac Pro… and your old Mac Pro too.
