I just wanted to mention that the closer the fan is to the holes in the top the louder it will be.

I was totally aware of this. The thing is, even at the fan's lowest setting, and even with it being moved away from the holes, it was still too noisy for my tastes.

Add to that the fact that, if you move it away from the holes, less air actually gets blown out of the casing. When I moved it away from the holes, I couldn't feel any air coming out of them (fan was oriented to move air up and out of the case).
