I never imagined the fun I would have from modding my Xbox.
I started with a mod chip and then progressed to modding the jewel and controllers.
I have also upgraded to a 80mm fan but I am undecided to power it off the MB and control it through Anod-X or attach it to the power leads for the harddrive and let it run at full speed.
