What you would lke requires you to buy a mod chip...$50-90, depending on which you get. Some decent sodering skills (screw up, and your XBOX is useless), and any sized HD. After all hardware is completed, you need something like AVALAUNCH as your dashboard, flash your bios, and your set. Xbox-Scene.com has some good tuts. But also, which ever Modchip you purchase, 99% of the time, their site has a COMPLETE tutorial on how to apply the chip (even a different tut for each version of the XBOX).
