While inheriting the basic functions and design philosophy of the current PlayStation 2 (SCPH-50000) the internal design architecture of the new redesigned PlayStation 2 computer entertainment system (SCPH-70000 CB) model has been completely overhauled resulting in a slimmer and more lightweight form. Internal volume has been reduced by 75 percent overall weight has been halved and thickness trimmed down to 2.8 cm (thickness of current model is 7.8cm). Its size is almost as small as a hardcover book making it easier to carry around.
