In September 2004, Sony unveiled its third major hardware revision to the PS2 line. Available in late October 2004, it was smaller, thinner, and quieter than the original versions and included a built-in Ethernet port (in some markets it also had an integrated modem). Due to its thinner profile, it did not contain the 3.5" expansion bay and therefore did not support the internal hard disk drive. It also lacked an internal power supply until a later revision (excluding the Japanese version), similar to the GameCube, and had a modified Multitap expansion. The removal of the expansion bay was criticized as a limitation to software, due to the existence of titles such as Final Fantasy XI, which required the HDD use.
