Check out the official unboxing video for the New PlayStation 3 Bundle, right here on Fan Reviews.
PS3 CECH-4000B consoles (those with hard drives) weigh approximately 2.1 kg (4.6 lb), while the CECH-4000A weighs approximately 2.0 kg (4.4 lb).[99] Both will be ≈25% smaller and ≈20% lighter than the original PS3 Slim. This version has a sliding disc cover rather than the slot-loading drive found on previous PlayStation 3 consoles.
