Experience huge savings on iMac!

Any iteration of iMac is a fantastic all-in-one machine, and when purchased through MacSales.com, you can count on all the horsepower at a fraction of the price of buying new. Add this 2017 iMac to your workflow at dramatic savings!

Talk about oomph. This baby has some power and then some. More processor cores equals more tasks and projects you can do at once. And with a Turbo Boost up to 4.5, you will definitely have enough power for years to come without feeling like your processors are holding you back.

16GB of Memory

This iMac is champing at the bit to get to work. With 16GB of memory you can multi-task with efficiency and experience less lag time with launching and saving applications. If you need more memory, you can expand to 64.0 GB with this model iMac.

2.0TB Fusion Drive

This machine comes with a 2.0TB 7,200RPM hard drive and a 128GB Flash storage module that work in tandem as a single volume. Fusion gives you roughly the performance of an SSD, while also taking advantage of the plentiful storage of platter-based drives.

Gigabit Ethernet, Wi-Fi, and Bluetooth Networking

This iMac, in addition to the one RJ-45 port that supports 10/100/1000BASE-T networks, also has a Bluetooth 4.2 and 802.11a/b/g/n/ac Wi-Fi card installed. So you're covered for all your wired and wireless connection needs.

Reviewer: edweb

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)

Rating: 5/5 Great Experience! June 5, 2020 I ordered a refurbished 27' 5k iMac a few months ago from OWC/MacSales. It has been working great! The price was probably half of what I would have paid had I purchased new, plus I was able to max out the RAM and SSD storage to get exactly what I wanted. Because computer performance and software has largely stabilized, it is no longer necessary to have the newest computer on the market to have great performance. In fact, I get better performance from my OWC refurb iMac (because I was able to max out the specs), than I would have if I had compromised and ordered the latest from Apple with fewer options. Thanks OWC!

Rating: 5/5 Would and will order again from OWC. March 23, 2020 New iMacs and the Catalina OS were not appealing to me because I enjoy and find important a couple of 32 bit software programs.With delayed deliveries of parts and completed machines occurring early in the pandemic, I decided to look at an OWC spec'ed iMac and the 2017 with some desirable added memory and storage was just the ticket. Ordering online was simplicity itself and the machine arrived safely and has performed flawlessly. The Parallels bundle was a good deal, too, so the iMac runs a speedy WIn10, too.

Rating: 5/5 Great Replacement for an Old iMac January 24, 2020 Last week, the motherboard on my 11,3 2010 iMac went South. I didn't realize how reliant I am on my Mac, so based on previous positive experiences with OWC, I visited their website to search for a refurbished iMac. I liked the fact that I was able to customize my new machine, and purchased this model with 32 GB RAM and a 1 TB SSD. My new iMac is much faster than the one it replaced, and I absolutely love the Retina display. My sales experience was flawless; the guy who assisted me was knowledgeable and friendly. The entire interaction/transaction was great, and I received my new iMac in two days via ground shipping. Happy to have saved a bit of money while concurrently being able to configure my iMac to meet my needs.

Rating: 5/5 Silent Power from Beyond December 29, 2019 This was basically a brand-new, custom-built iMac at a massive discount. The machine is silent, powerful enough (3.8 mHz) to run X-Plane effortlessly. With 32 GB RAM and a Fusion Drive, it's like everything is in RAM already. Click an app and it's on the screen instantly. Tap the space bar and it wakes up instantly. The rechargeable keyboard & mouse are so nice. One charge lasts weeks. No more buying batteries! (Note: The reason the mouse can't be used while charging is that if it was plugged in while in use, the electric cord would get bent back and forth so much it would break.) We love this machine. ??
