Hi, my new iMac 27" is coming in the mail later this week. I am moving off of a Hackintosh and all my files (not including Operating System and Apps installed on a SSD) were installed on a 3tb internal 3.5" HDD. My new iMac 27" was BTO with a SSD which I plan to just keep Apps and the OS install on. I would like to get my files (iTunes Library, iPhoto Library, Downloads, etc.) onto the new iMac without buying too much more stuff. I eventually plan to buy a different and larger capactiy External HDD but is there currently a single enclosure for my existing 3.5" HDD to go into a thunderbolt port? Thank you.
