Tim's next F U to Job's legacy. Job's wanted all of their devices to be visually similar as far as pixel density, resolution, and panel technology so that if you look at an image on one device, it will look the same on the other. But nah we need to bring the old "Apple tax" fodder to a whole new level. Ironic, as they go back to an iPhone 4 like bezel, you know, during the time Job's was still innovating.

Tim has ruined Apple for me, and them switching to ARM used to excite me to no end. Now I don't care at all.

As a hardware nut, I think there's a small Apple tax on the entry level model but I think it's justifiable.

1) Motherboard is a custom large server/professional design, depending on how many layers as well, with the amount of supposed throughput, this makes sense.
 2) Full PCIe 4.0 out of the box, only Raptor Computing has "consumer" level PCIe 4.0 alvut calling it for consumers is very generous. AMD has some boards supporting PCIe 4.0 but they need BIOS updates to enable it.
3) Custom PCIe MPX slots for beyond standard PCIe 4.0 speeds. For the target audience this garuntee's they will have the fastest graphics bus for at least a few years.
4) Compactness of on board components takes some R&D. For example there is a ton of room in that chassis, slim 1400 Watt PSU and 8 total on board x16 slots.

I'm assuming the board costs around $2k-$2.5k, adding base level components and small apple tax, this cost is actually pretty justifiable. 

The ONLY downside I see is, nlike AMD's AM4 sockets, this board is held back by the possible available CPU's it can take in the future. You get a 28-core Xeon, 1-2 years from now Intel jumps to 10nm lithography (CPU transistor size) and releases another chipset with double the horsepower. Many others will be able to upgrade the CPU more cost effective, however the Pro's main board will still probably be better than what most people could buy or afford.
