Does it really take much to maintain a user modifiable tower? I imagine the amount of engineering the 2013 Mac Pro took, was greater than simply maintaining a 4x PCIe slot box with whatever the latest and greatest Xeons are. Apple could have left the tower exactly the same. Problem solved.  It&#x27;s not sexy, and its not exciting but it&#x27;d keep a very dedicated group of Mac buyers happy and married to the platform.<p>It isn&#x27;t mutually exclusive to cater to both audiences.
