I am not quite sure, I dont do much of this, but I am pretty sure if you were to remove the current fans and replace with the tailsmoon fans, then put the other fans on the dvd drive, or the same power as the tailsmoon, then hook the case lights to the dvd drive, you should have enough power.
Dont quote me though, I dont do this kind of stuff, but I have seen people with many more things in their xbox's that that.
hook the lights and the larger fan to your bottom right hand corner of your dvd drive and ground wire to the frame. you should be fine. i had one running this much power with no problems.
There's also a board out there that gets soldered into certain points on the board that have power but aren't used to provide you extra outlets for all of your toys!! I would give you the link but I can't seem to find it at the moment.
