The PS2 reference in dialog does not refer to the Sony PlayStation 2. The PlayStation 2 wasn't released in Japan for another 4 months and not in North America until Oct 2000, nearly a full year after the episode aired. The dialog is actually referring to the IBM Personal System/2 or PS/2 released in 1987, 12 years before this episode. It was not discontinued until 1995, 4 years before the episode. It has a modular and mostly screw less case that made dis-assembly/reassembly races a computer nerd pass-time.
