Third-Party RAM for 27-inch iMac Still Far More Affordable Than Apple's Checkout Upgrade Options
Apple yesterday announced a new 27-inch iMac with faster 10th-generation Intel Core processor options, next-generation AMD graphics, and up to a whopping 128GB of RAM.

To max out the RAM at checkout, Apple charges an additional $2,600, which is like buying another whole iMac. Fortunately, the memory in the 27-inch iMac is user-replaceable thanks to the easily-accessible memory backdoor slot, and there are far more affordable options available from third parties.
OWC offers 128GB of DDR4 PC4-21300 RAM that's compatible with the 27-inch iMac. The total cost on Amazon is $599.99, or $2,000 less than Apple charges its customers. These are the OWC memory upgrade kits available, compared to the prices that you'd pay when purchasing an iMac from Apple:
Apple provides instructions for users wanting to install memory in an iMac. Note that the RAM in the 21.5-inch iMac models, which were not updated yesterday other than a change to the base storage configuration, is not user-accessible.
