I intend to support it in some fashion (like velcro as charlesrshell previously suggested), but I don't intend to incorporate it into the shelving on my media center. I prefer the clean look so all cables are located behind it.If you keep dangling your dongle it might fall off or get weak at the stem.
* A friend of mine custom made this cabinet for me from hickory that he cut, cured, and planed himself.
