Marques Brownlee has had the new iMac Pro for about a week. In the video embedded below, he shows it off, shares his first impressions.

If you are in the market, this is absolutely worth your time.

Couple of notes here:

• Important to note that the new iMac Pro is not user upgradable. So if you are ordering, future proof best you can.

• Marques priced out a home built PC using the iMac Pro parts (or similarly specced parts where the actual parts are not yet available) and came up with a price of $5100. Comparing that to the iMac Pro base price of $4999, my take is that the iMac Pro is fairly priced.

• The fact that I cannot upgrade over time is an issue for me, though I suspect iFixit will eventually sell a kit to get me inside and 3rd parties will sell parts to upgrade. Eventually.

• The iMac Pro is very quiet, runs cool. That’s impressive, given the high end workstation grade parts jammed in to that svelte enclosure.
