This board gets us a lot for the price:

• Dual Intel 10G LAN ports
• Up to 128 gigabytes of RAM in eight slots, with DDR4 3333+MHz support
• 4-Way PCI-E Gen3 x16 link supporting NVidia GeForce SLI and AMD CrossFireX on demand
• U.2 and M.2 drive support
• Easy overclocking

Eye-watering price for a stick of RAM, but you can always add more if the budget allows.

We need a terabyte of fast storage, so we have to go for the Samsung 960 EVO M.2, a rock-solid, super-reliable drive that will make sure this build doesn't have any bottlenecks.

This is where we have to make a deviation from the iMac Pro because Apple has announced that it will be powered by AMD's Vega graphics chip, but cards featuring this GPU aren't out yet, so we're going with the GeForce GTX 1080 Ti as an alternative.

This system is going to need a powerful and stable PSU to make sure that it can deliver the performance where it's needed. The EVGA SuperNOVA can not only deliver the watts when they are needed, but it's also highly energy efficient and comes with a 10-year warranty.

Unless you're going to run all the parts in a cardboard box, you need a case, and the NZXT H440 has a lot of features that I like:

• Plenty of cooling
• Space for 11x 3.5-inch or 8x 2.5-inch drives
• Sound dampening
• Rolled edges so you don't rip your hands to shreds when building or upgrading it)

OK, it doesn't look like an iMac; I think it looks better.

This display isn't encased in brushed aluminum, and we can't shove all the other components into it, but this display makes an awesome centerpiece to this build.

• Pin-sharp 5120 x 2880 8ms display
• IPS technology
• 1.074 billion colors
• 2x DisplayPort
• Mini Display Port
• USB3.0 Hub with three ports
• Adjustable height, pivot, swivel, and tilt

That Xeon chip doesn't come with a cooler, so we need to add one to the build. This Noctua is not only efficient, but it is also low-noise, which means your PC won't sound like Air Force One taking off.

Price: $55 | More info

If you want Thunderbolt ports, you'll need a Thunderbolt add-on card since there are no Thunderbolt ports on the motherboard. However, if you don't need these ports, fee free to leave the card out of the build.

Apple's iMac Pro ships with a Magic Keyboard which features a numeric keypad, and a choice of Magic Mouse 2 or Magic Trackpad 2. However, you're free to choose whatever suits your needs.

Price: Around $200 for Apple peripherals

The final piece of this PC is a copy of Windows 10 Pro.

Price: $140 for OEM, $199 for retail copy

While there are clearly design differences, and we can't get out hands on any AMD Vega GPUs, from a hardware perspective this system ticks most of the boxes -- it's a Xeon-powered PC with 32-gigabytes of RAM, a terabyte of fast M.2 storage, and a spectacular 5K display.

But what's the price?

Believe it or not, the final price for this system comes in at more than the base iMac Pro -- $5,500 plus change. You can probably do better than this by shopping around (these prices listed are averages), and if you are able to do with a 4K display instead of a 5K unit, then you're looking at quite a saving.
