Originally, I planned on doing LEDs for the case lights, but i found it much easier to add a 12v source from the motherboard and run white cathodes. For adding the 12v source, I used
this tutorial on how do add the line for the cathodes.
pictures for your viewing pleasure:

note the 4" cathodes on the left and right side, and the added switch above the power to turn them on/off

Right side

I chopped open the connector box so i wouldn't be so big

shot of the connections: v2



Humpty is all put back together; i also added the Talismoon Crysal Flow fan duct, so the fan LEDs will show better
