i've had an a500 and i've seen my friends q500 and s500 the inner metal is the same color, my color blindness probably makes me think its goldgreen. BTW the bezel on the v500,q500,a500,s500 is the same style. Has a rectangular button, followed by a vertical triangular groove with 2 clear plastic lights, then a reset. the groove runs down to the bottom. The a500 has a sliding mobo try, the v500 doesnt, the s500 doesnt. I dont know about the q500. Also they all have a little lock hold in the back for a cable and lock.
