It is perplexing to see all of the 5.25" drive slots in modern cases. A few years ago, everyone wanted two optical drives for copying CDs and DVDs, but today, everyone I know has one optical drive or somehow scrapes along without one. The argument against optical drives is that you can live without one in the world of online software market places, like steampowered.com and direc2drive.com. Try installing Windows without an optical drive. Sure you can do it by using tools to spin up a USB boot drive, but for the price of $20, you avoid those headaches. With a single optical drive, or none, most users end up with quite a few free 5.25" drive bays.
Computer manufacturers and case makers have been working on cleaning up the internals of PCs for years. We've seen hot glued drive connectors, weird multi stage tray systems, a plethora of different drive cage and all sorts of other inventive solutions. Nothing really has stuck though. The next great case always seems to improve on some things and then drop the ball on a few. That is why we need companies like Icy Dock to pick up the slack!
The Icy Dock MB973SP-B is used to convert two 5.25" drive bays into three 3.5" bays, while adding some additional functionality. The Icy Dock MB973SP-B comes with a number of useful secondary features, such an eSATA port, USB Port, selectable cooling profiles, hot swap SATA support, and Xpress TRAY-LESS SETUP. With unique styling and SATA 6.0Gbps support built in, the MB973SP-B looks ready for the future.
