PS2 Slim (2004)

A smaller, lighter, and less-expensive version of the PlayStation 2, this unit was widely known by its unofficial name, the PS2 Slim. Part of the thinning-down process included moving the power supply transformer to an external brick, and trading the slot-loading drive for a top-loading one.

A handful of games, such as Final Fantasy XI, which made use of the sold-separately PlayStation hard drive, could not be played on the PS2 Slim, as it lacked the requisite expansion bay.

The Slim hardware underwent several minor revisions itself, and ended up weighing less than one-third of what the original PS2 did. Another variant, called the PSX, was briefly sold only in Japan. It combined a DVR and DVD burner with PS2 game support.
