Unboxing and Teardown of the 2017 27-inch iMac with Retina 5K

[Update 06/09: Unboxing, Teardown of 2017 21.5-inch iMac (Non-Retina Model)]

Among Apple’s hardware and software announcements at Monday’s Worldwide Developers Conference were updates to the iMac line. We were able to get our hands on a base model 27″ iMac with a 3.4GHz quad-core Intel Core i5 processor, and in addition to confirming that the model is compatible with up to 64GB of RAM, we completed a teardown of the iMac to give our readers an internal look at the new model.

Check out the video below for the complete teardown of the 2017 27-inch Apple iMac:

  • How fast is the spinning drive in the fusion drive for 27″ iMacs?

  • Is the CPU replaceable, right? The 21,5″ iMac 2017 has no soldered CPU, so it might be upgradable I presumed.

  • I know that you can’t upgrade the SSD in the card slot but you can upgrade the regular hard drive to SSD.
    So, if you order the iMac with a 512GB SSD, is it a 512GB PCIe card in the card slot and an empty hard drive or is a SSD hard drive? Also how does the PCIe card slot memory work if you add a SSD drive. is it ignored or used?

  • Just an FYI, the chip you identified as the CPU is actually the GPU and the chip hidden away under the heat sink is the CPU.
    Take care~

    • Yup, you’re absolutely right, and great catch. Dave actually caught that too right after the video was produced. He did a little facepalm, but it’s ok, these things happen in the heat of taking a great new iMac apart. Thanks for watching and the helpful comment!

      • Hi, does thát suggest that the CPU is (/or is not…) user replaceable….?

        (I accidentally ordered the computer with i5, just to realize that I probably will need the i7, expensive mistake…).

  • Can you please confirm whether the stand mounting hardware is identical to previous versions? I have a custom adapter from Monitors in Motion and would like to know if I can use that or have to go with the built-in VESA mount.

  • Does OWC offer replacement/upgraded SSD cards for this model (and late 2015 models)? Wasn’t sure if they are proprietary parts or not.

    • At this time we don’t offer replacement PCIe SSD cards for installation into the card slot. However, we do offer 2.5-inch SSD upgrade kits you can use to swap out the main drive with a super fast SSD. It’s also an easier install, as you can access the main drive right after you get the iMac screen removed, versus removing nearly all the internal boards which is required to access the PCIe slot.


      If you don’t want to dive into taking your iMac apart you could also connect an external SSD equipped Thunderbolt drive

      Hope that helps.

      • There are adapter cards that convert Apple’s proprietary SSD card slot into an mSATA slot. You can then use common mSATA SSDs. I am not sure if they are compatible with the 2017 iMac. They were compatible with the 2012 iMacs. MaxUpgrades made one and so did MicroSataCables.

  • Great. Thanks.

    First video above:
    Apple Fusion Drive with Seagate HD part (can be removed): 6:56
    Intel microprocessor (seems fixed): 10:05
    Apple Fusion Drive with Samsung SSD part (can be removed): 10:26

    But where is RAM on first video? Can it be removed?
