I find OWC prices on memory and traditional HDD's a bit expensive. But I do love the service and found the optibay solution as well as external HDD enclosures to be of pretty good quality. If all you are doing is memory and a 500gb HDD, you can find better prices and good service from Newegg or Amazon or even Buy.com. But if you want an SSD, enclosure for your old HDD to use it as a back up or clone and or an optibay solution, I would go OWC, it is what I did, but my memory cam from buy.com as they were $40 cheaper for Kingston ram than anyone else.
