In order to get a feel for placement go through a few dry runs. Led fans are great at the back of the case. Maybe a 12-inch tube mounted to the bottom and two 6-inch tubes at the top so you can position them for better coverage. I currently have 1 red LED cannon pointed towards the HSF from a front bay, 1 blue cold cathode attached to the bottom and two 6-inch blue cold cathodes (one attached to the top of the case and another in a 5 1/4 bay.) The red shows off the the cpu and RAM with the blue color from the top and bottom sort of bracketing it.
I read two reviews of your Chaintech\Zenith MOBO today. Looks like a GOOD choice!
