Xbox Mod: Xbox Media Center (Xbox Only, Not Xbox360)
Game console can be altered to do more than play games ; Xbox Media Center. The Media Center turns the game console into a complete multimedia center.
Sure, it was cool to install the mod chip or by just Softmod, add the EvolutionX interface, and upgrade the hard drive. But the Media Player lets you load the Xbox up with all kinds of software and files (the reason why we upgraded the hard drive in the first place).
