Like I did with the Mac Mini, I found some concept arts of what a future Mac Pro might look like. I figured the people here may get a kick out of it. Some of these might be old ones but I like the idea of them nevertheless.
For me, the reason to buy a Mac Pro is upgrade ability. All those concept art pics appear to lack space for PCIe cards (especially graphics cards). And they look challenged for drive bays.
That’s the entire idea - don’t make space for GPUs then those pesky third party folks won’t find unknown creative ways to make them work!
Additionally, lock people to a spec so if they want to to upgrade they have to spend another $20,000 on another new computer rather than just upgrading the memory for instance.
