Just curious... I've heard of a few people asking about adding an SSD drive to their 27" iMacs that were ordered with a 1TB drive but I haven't seen anyone ask whether it is possible to add a 2TB drive after selecting an SSD drive as your primary drive. Where do they put the SSD drive? In the spot where the 1TB drive was supposed to be or in the spot where the SSD drive would go if you had ordered both the 256GB SSD and the 1TB SATA HDD? I'm contemplating buying the 256GB SSD and then adding a 2TB drive on my own. Anyone have pictures of an iMac with just the 256GB SSD drive in it?
