Can the storage or memory in a iMac (Retina 5K, 27-inch, Mid 2017) be upgraded?

The iMac (Retina 5K, 27-inch, Mid 2017) is an Intel Mac from before Apple soldered everything down, so on many configurations the storage and sometimes the memory can be upgraded, and an SSD upgrade is often the single most transformative repair on a machine of this age.

The jobs we see most on the iMac (Retina 5K, 27-inch, Mid 2017) are ram upgrade, hard drive/ssd replacement, display replacement, power supply replacement. Apple rates this model's service difficulty as advanced, and we diagnose every machine on a bench supply and under a microscope before quoting, so you get a fixed price for the actual fault rather than a guess. Diagnosis is free.
