Apple are continuing building smaller, and not bigger. The iMac can be overpowered to beat that "trash can". Apple even dropped that beatuiful 17"-MacBook-Pro laptop years ago. They also dropped their external hardware-Fusion-Raid enclosures,..., years ago as well.
I suspect Apple is out of the Workstation/Server market for good, -they'll update the iMac instead.
They even admit their money is mostly on the iPhones, iPads, ..., and will continue to be so.
Apple really has NOTHING to offer Workstation/Servers, -they had a chance, years ago, to go with ZFS,..., but Steve Jobs was either to cheap to pay, that Sun-killer, "Oracle", or he knew that the Desktop/Laptop market was a dead-end for his over-priced Apple's.?
And Apple's "HFS+" file system is a piece of ■■■■ anyway. which everybody knew then, and now.
