It may be a sealed unit. In that case, taking it apart would be a less than stellar option, much like the pro mice and mighty mice. The easiest thing to do would be to mask off the transparent black fronting, sand the whole thing lightly, and then spray it with a half dozen coats of matte black. then re-sand it smooth, and hit it with a matte clear. One more sanding, and you're probably home free.
