In September 2004 Sony unveiled its third major hardware revision (V12, model number SCPH-70000). Available in November 2004, it is smaller and thinner than the old version and includes a built-in Ethernet
port. In some markets it also integrates a modem
. Due to its thinner profile, it does not contain the 3.5" expansion bay
, and therefore does not support the internal hard disk drive
, and now uses an external power supply, like the GameCube
. The removal of the HDD bay has been criticized as a limitation  due to the existence of titles such as Final Fantasy XI which require the use of the HDD.
The official PS2 Linux
kit also requires a hard drive bay to function. The SCPH-70000 is also the only series to work with the MultiTap expansion allowing 4 players to play at the same time. Third party connectors can be soldered into the unit giving hard drive support, however IDE connections were completely removed in the V14 revision eliminating this option.
