Kinda, when you remove the top mesh filter you will see a "drop-in" housing your RAD and top fans will go in there, and the "lip" that holds the RAD in place will have the 2nd bank of fans attached to it. You have to use longer fan screws as they have to clear about 5--6mm of lip space. Unless you have seen the case it is hard to describe, but once you see it you'll know what I mean.
Now below the Lip you attach the 2nd batch of fans, so they are technically not attached to the RAD but they are attached to the case, just below the RAD. This give you the ability to use a a thicker RAD, but if you like the industrial look you can go thicker as the fans will stick out of the top of the case.
Also remember that you can break the loop...
