Apple's iMac Pro model number pegged as 'A1862' ahead of expected Dec. launch
While little else solid is known about the iMac Pro's shipping configuration with only a matter of days before it ships, it appears that a regulatory filing associated with the device calls it model A1862.

The Eurasian Economic Commission filing was first spotted by Consomac on Thursday morning. The filing, calls the device a Mac desktop computer running macOS 10.13 labeling it with model number A1862.
The filing date for the computer was November 23. The same agency heralded most of the 2017 WWDC announcements in a similar fashion in the days before the event.

The iMac Pro made a brief appearance at the 2017 WWDC. It will feature a 5K display, Vega Graphics, up to 18-core Xeon processors, up to 4TB of SSD storage, and will start at $4,999 when it ships this month, before the end of the calendar year.
A pair of developers expect that there will be an A10X fusion processor in the iMac Pro to facilitate "Hey Siri" and other boot-related tasks.

The only 5K monitor you will find is actually the one LG partner with Apple. Dell said they would ship one long ago but nothing has happen. Many guess it was simply a problem of price and market fit.
And when you factor in the all in one, metal casing, and Keyboard and mouse, it is actually fairly attractively priced.
The problem is, do you value the screen and Display? Do you value the high machines Aluminium casing? The speakers, the keyboard, etc.
The problem with iMac is not many wanted to pay the premium for the screen. That is llke not everyone are willing to spend 2K+ on a OLED TV.
I for one wanted the same two side cooling system for an high end CPU and GPU without going into server and workstation parts, and 2K 21" Screen will do me fine.
Unfortunately, Apple doesn't offer much choice for Desktop.
Apple did one during the keynote with an HP Workstation and it was over $7,000. I think we'll have to wait a little bit when the parts become fully available for the public.
What many fail to factor in when calculating a cost is the R&D, engineering, making the software all work efficiently, the OS, and any apps included, assembly, shipping, retail, support costs, etc. These are all factored into the cost of any product, yet people just go on PC Part Picker and price out the parts and think thats a fair comparison when its not.
In the end, building one's own PC with similar parts got within a few hundred dollars of a iMac Pro, assuming one's time assembling/configuring/testing the machine was not factored in, in addition to not having a warranty like Apple would have.
iHaters claiming an "Apple Tax" just have zero cred to debate with. This machine is going to sell like crazy.
As for a breakdown of components in order to calculate the price; you sir are spot on.
Intel Xeon (8 core / 16 thread)
32 GB DDR4-2666 ECC
1TB SSD
Radeon Pro Vega 56 - 8 GB HBM2
DIY PC ($3090 - everything except for a monitor, keyboard, mouse and OS)
AMD Threadripper 1950X (16 core / 32 thread)
32 GB DDR4-2133 ECC
1TB Samsung 960 EVO
Radeon Vega Frontier Edition (Vega 64) - 16 GB HBM2

The DIY build has a better CPU and GPU than the iMac Pro.
By the time the iMac Pro launches, there will be even more price drops and other new products only a month or so away (look to CES).
Uh, that's sort of a big deal when comparing to an iMac dude.
Heres another PCpartPicker estimate from june which included a monitor:
Total: $4686.71
http://www.pcgamer.com/apples-new-imac-pro-costs-5000-but-is-it-overpriced/...but again, this assumes your time has no value, that a single provider warranty has no value, and ignores the awesome longevity, resale value, and lower TCO of a Mac. A Mac’s value is more than a bunch of PC parts slapped into a case.
This is the typical bullshit response. Its no where near an actual comparison. You're forgetting most Professionals don't want to fuck around with finding the parts, making sure they're all compatible, building the PC, installing the OS and all of the drivers, supporting their own PC when issues arise, etc. They just want to take the damn thing out of the box, install the software they need, migrate files if necessary and be on their way. When something goes wrong they have full support from Apple. Good luck with that on your build where you have to call individual manufacturers to get...well some kind of support for it.
You left out a display which is a critical component to your build as its not going to be cheap to find a compatible display. You left out Thunderbolt 3 and if you don't think thats a big deal then you're completely full of shit. Its not running macOS which can be critical for a lot of Professionals.
Its more than just the sum of the parts...its the experience, the support, etc. You can't PC part pick that...
Outside of the keyboard, mouse, OS and monitor, what major components am I missing?
There are also trade-offs for the warranty, while it's not through a single company, the duration on individual parts is often between 3 and 7 years.
Putting this together will take 15-20 minutes. One would end up saving more time because they'd have a faster machine.
You wouldn't need to worry about resale in the short term because you'd have a system with 64 PCIe lanes, 4 PCIe 3.0 x16 slots, 1 PCIe 2.0 x1 slot, 3 Ultra M.2 ports, 1 U.2 port, 8 SATA3 ports and 8 memory slots. It's easy to just upgrade.
I left out a display on purpose, I even made note of that. Now you have $2000 to spend on a display or multiple displays.
Thunderbolt 3 isn't that important when you have a motherboard with 64 PCIe lanes and loads of ports/upgrade options. External GPU? External storage? Just put it in the machine.
People joke, but a lot of the mess can simply go into the case.
Again, if you're looking for an "experience" with a singular warranty, the larger OEMs will have computers with similar specs in about a month.
Just in case it wasn't clear, the build I listed is also quite a bit more powerful than the base iMac Pro. To allow the iMac Pro to compete, you'll have to go well above the starting price.
Nobody cares about short term value...its the long term value. There are only so many things you can upgrade. 4 or 5 years from now the upgrade options will be just as limited as the the iMac Pro so you're not really gaining much there. The bus speed today will be just as slow today as it will be in 5yrs.
I seriously doubt the speed of this amazing CPU you keep pushing isn't enough to make up for the time spent to build the PC (which more Professionals don't want to do and will take most more than 15-20 minutes...thats BS!), the time spent troubleshooting issues, installing the OS and the apps they need, etc. As I said before, there are a lot of Professionals who already use a Mac so why would they go through the pain of switching to a different platform, building the PC (if they even know how), installing the OS, etc?
How about the experience of using a Mac? The integration of Apple services and other hardware? What part is 7yrs on the warranty in your build? And don't tell me the case either. As said by @StrangeDays, there's a hell of a lot more to a Mac than just the sum of its parts. If you just want to be a BestBuy geek and just worry about specs then be my guest, but there's a hell of a lot more to a computer than the specs.
