        Rating: 5/5 Excellent second-hand iMac October 31, 2021 Replaced my 12,2 iMac which could no longer cope. Very pleased with this purchase, despite some unnecessary complicated customs delay (shipping outside U.S.). Some minor cosmetic wear & tear on the machine. OWC upgrade to 2 TB SSD (although I did not know it would be a PCI-Ex disk......which however means I can use one of my "old" SSDs and add even more storage). Upgraded OS to 11.6, performance is still excellent, perfectly sufficient for a few years to come (or at least until Apple drops Intel support completely)

        I would recommend this item to a friend! This review is from Apple 27" iMac Retina 5K (2017) 4.2GHz Quad Core i7 - Used, Excellent condition.

        Rating: 5/5 My used 27” iMac from OWC looks like new! June 24, 2021 My new to me 27” iMac was customized to perfectly meet my needs (32 GB memory, 2TB SSD hard drive). The way it was packaged for shipping was amazing! Minimal but extremely sturdy support that kept that big monitor from torquing in transit. I’m loving my iMac!
