I found a custom workstation that can be configured similar to an iMac Pro here.
Here is a comparison I made:
Xeon 8-Core W-2145 CPU: $1315
CPU cooler: $115
Gigabyte C422 motherboard: $629
32GB of Samsung DDR-2666 ECC RAM: $388
AMD Radeon Pro WX 9100 (Vega 64 16GB) GPU: $1700
1TB Samsung 960 Pro m.2 SSD: $668
850W PSU: $165
ATX case: $110
LG UltraFine 5K Display from Apple Store: $1,299.95
Magic Keyboard with Numeric Keypad from Apple Store: $129
Magic Mouse 2 from Apple Store: $79
Total = $6,597.95 plus a little extra for power & video cables etc. (That's just the price of the hardware for a DIY build.)
Base iMac Pro with Pro Vega 64 16GB: $5,599
