The not-yet-available 27-in. iMac will continue to sport four external memory slots. Customers can boost the RAM at the time of ordering to 16GB (for an extra $200) or 32GB ($600), but those prices are exorbitant compared to third-party RAM that users install themselves. An additional 8GB of memory -- which would raise the iMac's total to 16GB -- costs just $40 at Crucial.com, for example.
iFixit spotted several other changes to the iMac, including a larger, single fan rather than several smaller fans; dual microphones, likely a noise cancellation move for FaceTime video calls; and a vibration-dampening housing around the laptop-sized 2.5-in. hard disk drive.
The teardown also exposed the location where Apple places a "Fusion Drive," the option that combines 128GB of flash storage with a standard platter-based hard drive.
The new iMacs are priced between $1,299 and $1,999 -- $100 more than their precursors -- and can be purchased or pre-ordered at Apple's online and retail stores.
iFixit reduced the repair score of Apple's iMac from 7 to 3 (out of 10), citing screen-to-chassis glue and the impracticality of upgrading RAM or swapping drives. (Image: iFixit.)
