My original plan for airflow in my case has gone down the drain because I can't position one of my radiators where I wanted to initially. My new plan is to have four 120mm fans at the rear of the case as intakes with 480mm rads on the left and right. I'm hoping that the unimpeded flow from the rear fans will make up for the eight fans which will be pushing air out through radiators so that I can maintain positive air pressure. Am I beinng overly optimistic?

I'd say with a 2-1 ratio you may be OK depending how restrictive your rads are but unfortunately the only way to know for sure is to try it for a while and see how the dust build up is.
 
What Mikey C said. Very hard to guess, but I would error on the side of more case intakes .. like at least 2 more. In fact I would line the back with filtered intakes. With the same spacing as your drawing that would be 7x 120mm fans.

I'd love to do that, but unfortunately the case only supports four fans at the back.
 
I really think you will be fine with a 2:1 ratio if the fans are the same. I'd recommend getting higher airflow fans for the intakes though if you want to be cautious.

But then again, if you are happy to bust out the dremel then I'd hate to get in the way of that :P

The dremel is always the correct option.
 
The fans on the rads are Akasa FN058 Apache Blacks and the rear intake fans are Corsair ML120 Pros.
 
Okay, well the ML120s have much higher airflow than the Apaches AND the Apaches will be on radiators, so I'd say you will probably get positive pressure in there.

Again though, if you want to be sure, taking a dremel to the case and making it your own is always a good choice!

Can't argue with that! I've already attacked it with a Dremel because the design of the case means that my GPU water blocks would fit, but I couldn't plug anything into them!! Hopefully that problem has now been remedied, but I'm not going to rule out some extra air holes if necessary :p

It's a very cool case concept-wise, but depending on what you want to do with it there are definitely compromises to be made!
