Apple’s new 21.5-inch iMacs are ridiculously thin and gorgeous. They’re also one of least upgradeable/repairable desktop computers on the market. It’s possible to swap out the RAM on the new 21.5-inch iMacs, but trying to get an aftermarket SSD into the 21.5-inch iMac might be an impossible task.
Teardowns of the new 21.5-inch iMac revealed that in order to get to the hard drive users will have to separate the display from the main body of the iMac. That task isn’t too difficult, but gluing the display back onto the iMac’s body will be pretty tough. On top of that, once you get inside the 21.5-inch iMac there’s literally no room for an SSD and nowhere to plug it in.
