Greetings, I wondered if someone could help me. I purchased a new iMac (27-inch, Late 2013) with the Apple SSD and before I go through the trouble of opening it up (cutting the tape) to install a 3.5-inch HDD I wanted to see if anyone knew if the brackets that hold the HDD are inside or not. If not does anyone know where to buy them since I don't see any spare parts listed for this model on iFixIt or anywhere else. I don't have that much space and I'd prefer to install a 2nd HDD inside rather than having to mount an external disk. I'm quite surprised that Apple doesn't offer an option to include a 2nd disk for custom builds. Thanks in advance for your help!
