In order to conceal unsightly optical drives and other 5.25" devices, the right hand portion of the Ahanix D.vine 4 Home Theater Series PC Case uses a thick aluminum door. The door mechanism is rather simple and uses a series of magnets and hinges to stay secure. A light push on the top right corner allows for the door to lightly descend revealing the drive bays. One issue I did note immediately is that the door sits flush against the drive bays, which eliminates the use of any fan controllers or audio interfaces. The Ahanix D.vine 4 Home Theater Series PC Case supports a total of two external 5.25" drive bays for use with optical drives or a select number of additional 5.25" based devices. Absent are any quality drive bays for those using a single optical drive. Instead, a single push out disposable drive bay has been included. Users may have the option of using their own spare drive bays providing they fit properly.
