The set I received was not the same as pictured. To replace a drive in a 2010 iMac, you need a T8 driver and thermal cable. It wasn't in my kit either. According to the OWC website, I got a kit to add a drive to an iMac. Adding a drive is much more difficult than replacing it. To add, remove all of the screws that secure the motherboard, move them out of the way, and then connect the new data cable. This procedure is well beyond the skills of a beginner. I would recommend looking at the kits sold by iFixit. Please note that I called OWC support. They insisted I have the correct driver to replace the hard drive (T10). It definitely wasn't. The factory drive bolts are T8, as a quick Google search confirms. I would only recommend this kit if you are sure you want to add a drive. Second, Mac OS works very well with two drives. Boot drives are easy to swap if you really need two. Just remember like I said above that adding a drive requires installing a new drive in the case and involves moving the motherboard around with cables all over the place.
