Obviously the original xbox is not being manufactured anymore, but for anyone who's interested here is a glimpse inside the Hungary Flextronics factory during the original Xbox's heyday.
Xbox was the first console to incorporate a hard disk drive, used primarily for storing game saves compressed in ZIP archives and content downloaded from Xbox Live. This eliminated the need for separate memory cards (although some older consoles, such as the TurboGrafx-CD, Sega CD and Sega Saturn had featured built-in battery backup memory prior to this). Most of the games also use the hard drive as a disk cache, for faster game loading times. Some games support "custom soundtracks", another unusual feature allowed by the hard drive. An Xbox owner can rip music from standard audio CDs to the hard drive and play their custom soundtrack, in addition to the original soundtrack of Xbox games that support the feature.
Original Xbox manufacturing stopped when Nvidia cease production of the GPU in August 2005, and in September of the same year Microsoft announced that they had lost Four Billion dollars selling the Xbox Console.
The Xbox will live on due to the huge homebrew and Linux scene that allows people to use the Xbox as a powerful media center amongst other things.
All in all its got to be a hardware and software hackers wet dream, a games console that runs on PC hardware.
