Here is a look at the Gun Metal PS3 Limited Edition Un-boxed up Close & Personal. It arrived today, and I -(as in Crazyglues from NG4.com) tried to take some really up close and clear Pictures to give people a better look at it.
From what I can tell it is in no-way shape or form Metal of any type. In-stead it seems to be a normal 40gig sprayed Gray. does not weigh more and feels in no way any different from a black PS3's plastic.
(Of Course this is my own personal opinion but hopefully the Pictures help you to judge for your self.)
