The new Apple iMacs were released just days ago, but iFixit has already ripped it apart for its usual teardown treatment. Both the 21.5- and 27-inch models feature the new 802.11ac wireless standard.
The 27-inch model features PCIe-based flash storage, which was first introduced into the MBA in June. The 21.5-inch model has a couple of changes from its bigger brother, where we have a new empty PCIe SSD, so that consumers can upgrade the based model iMac to the awesome Fusion Drive combination HDD/SSD drive that Apple released last year.
The CPU on the 21.5-inch model is soldered onto the logic board, which means there will be no upgrades on the smaller model. iFixit didn't seem too impressed with the 21.5-inch model, giving it a 2 out of 10 score for repairability for the soldered processor. The 27-inch model received a 5 out of 10 score.
