There will be many challenges for Apple as it designs the next generation Mac Pro. It will have to present with Apple’s unique design language, but the form will also have to follow the function as a modular device. For the practical minded user. The low end will have to be affordable, but it will also have to support the very best CPU/GPU/ and bus architecture. Here’s a concept video that pays homage to the (2008-2012) Mac Pro, has a modest desktop footprint, and still looks like it would be big enough to contain kind of power we drool for. Amazingly, it reminds me of HP’s Z2 Mini as well.
