Damn, dude. Nice snag on Magical Chase. Also, what edition of Xbox is that? I don't think I've seen that one before.
Maybe it's skeleton or skeleton green, but in weird light? Every time I see an Xbox in a weird case I've never seen before, I think of Ghostcase and other custom cases. Every once in a while you'll see a weird colored Gamecube and oh, it can fit regular DVDs? That explains it. Not saying this is a swap case. My guess is the light, since the controller cord seems green. Speaking of swap cases for the original Xbox ... Ghostcase
