Yes. Easy to identify by looking at the motherboard. Refer PS4 devwiki to see differences between 1000, 1100 and 1200 series. Another easy way to check is power and eject buttons. I think early 1000 series has touch sensors while later 1200 series has click buttons. Also Early 1000 series has 4 screws on back panel. 1200 series has only two screws in middle, the rest of chassis is held together by internal clips.
