Apple today updated its online store for refurbished products to add the new 27-inch iMac models that were first released in June of 2017.

This is the first time those particular machines have been available through the refurbished store since their introduction at the 2017 Worldwide Developers Conference. The iMacs feature Kaby Lake processors, faster SSDs, and AMD discrete graphics.

Apple has a dozen refurbished iMac models available at the current time, with prices discounted by approximately 15 percent. An entry-level model with 8GB RAM, a 1TB Fusion Drive, a 3.5GHz i5 processor, and a Radeon Pro 575 is priced at $1,699, for example, a $300 discount off the standard price.

Apple has a range of configurations available, from low-end to top-of-the-line. As with all refurbished products, stock will fluctuate regularly based on the machines Apple is getting in for repair.

All of Apple's refurbished products go through a rigorous refurbishment process before being offered for sale, which includes inspection, repairs, cleaning, and repackaging. Refurbished Macs come with a one-year warranty that can be extended with an AppleCare+ purchase. For more tips on purchasing a refurbished product, make sure to check out our guide.
