The new iMac, with its ultra slim bezel proved to be a disappointment to the iFixit team, because both the glass and the LCD are glued to the iMac frame with strong adhesive, which negatively impacts repairability.
The late 2012 iMac 21.5″ – code-named EMC 2544 – is an exercise in disappointment for us. We were quite worried when we saw that super-thin bezel during Apple’s keynote, and unfortunately we were correct: the glass and LCD are now glued to the iMac’s frame with incredibly strong adhesive. Gone are the lovely magnets that held the glass in place in iMacs of yesteryear.
While the RAM, hard drive, and CPU can be replaced, the entire logic board must be removed to do so, which led the iFixit team to give the 21″ iMac a repairability score of 3 out of 10, down from 7 out of 10 for last year’s model. [read]
