I've been a longtime OWC customer and have bought everything from SSDs, external enclosures, cables, etc and their products have always been on point. I recently got my hands on a used 2012 iMac and the first thing I wanted to do was upgrade the spinning HDD to an SSD. this kit had literally everything I needed to upgrade the original HDD and while I was in there I went ahead and gate the machine a good cleaning with an air duster and decided at the last minute to upgrade the blade SSD as well. with the SSD upgrades and maxing out the RAM @ 32GB, this machine has a new life. thanks OWC!

I would recommend this product to a friend!

Fast delivery, easy to set up

I'm happy that this little item is still available. Through this, I could service a customer with two older iMacs that badly needed hard disk replacement. So they were kept out of the let's-just-throw-these-away-box. Thanks for good service and fast delivery ! Karsten Franke
