Hmm... I know some of the 2013 models did have the access?

I am getting a 27"

For all of these 21.5-Inch and 27-Inch iMac models, Apple formally notes that the systems have "two 4 GB" of "1600 MHz DDR3 memory." However, for the 27-Inch models, Apple adds that these systems have "four user-accessible SO-DIMM slots."

Based on this information, EveryMac.com originally speculated that the 21.5-Inch models would have the RAM soldered onboard and only could be upgraded at the time of purchase, like the MacBook Air series.

However, after the "Late 2012" 21.5-Inch iMac models shipped, site sponsor Other World Computing disassembled one and discovered that it has two internal SO-DIMM slots (and subsequent "Early 2013" and "Late 2013" models are the same). Unfortunately, accessing these slots requires one to gingerly pry off the adhesive-attached display and remove the motherboard. By contrast, the 27-Inch models have a small panel that "pops off" the back with the press of a button. Needless to say, pressing a button to access the four SO-DIMM slots in the 27-Inch models is quick and easy.
