They took away the led strip and how do you change HDDs? I don't think it is fake because low res leaked images always look like crap. If we've learned anything from the PS3 slim fiasco, this is most likely real.
I do photoshop editing for a living and I'm not seeing much of anything in these photos that makes it jump out and scream fake. Gradients all seem legit, no obvious photoshopping. There's some sketchy noise around the PS4 logo, but other than that looks legit.
