After you unscrew the four attachment screws at the back, you can take the back unit out. You'll end up with the hollow aluminum casing and the back unit; which is attached to a small metal rack for accommodating hard drives. It slides out easily with only one cable attached. This cable is designed to supply power to the front LED and can be easily removed.
An important feature of the Eagle Consus I-Series ET-CSIU2J-BK is the ability to accommodate two hard drives. It only supports JBOD, which essentially combines two hard drives into one storage volume as detected by your computer. RAID is not supported; but we don't expect that feature at this price range anyways. From the photo above, you can also see that installation is relatively easy. You only need to plug in your SATA hard drive and then screw in the four standard screws on the side (These screws are included). Detailed instructions are provided just in case you are confused.
