Hello! Can anyone give an answer, is there a way, to install SSD-Drive in addition to my default HDD-Drive, without removing an Optical Drive? (iMac 21.5" Mid 2011). I can find only hdd-replacement or optical drive replacement tutors. I'm understand, that 21.5" iMacs haven't enough place to simply add 2.5" SSD, but, maybe I can definitely use SSD without body, like SSD-Drive that installed in MacBooks?
