Great design, I very nearly almost had this identical case submitted to Ben for my own custom case im getting fabbed... In the end I found with the top/bottom rad positioning the case became way too long for my tastes, and I was worried about stability when the rad (and all the weight) is up so high with the case being very thin it could become tippy, also if a leak occurs anywhere in the loop, you have all that water *ABOVE* the components. Plus I wanted a Horizontal MOBO mount so I could add panel mount barbs around the edges as needed and minimize tubing mess. With a horizontal mount you literally have the ability to mount coolant inches away from the source to the destination... all hidden.
Anyways back on topic,
When designing the rad mounts I struggled with the fact of making a case *just* for one specific radiator, after some simple measurements I came up with a very simple mod to increase radiator compatibility/flexibility. Drill out the screw holes on the rad brackets so they are oval shaped as so:

This will allow me to slide the radiator back and forth up to an inch in either direction to allow:
-wider pumps/tubing/LCD screen..whatever
-other brands of radiators with different hole spacing.
My design will fit up to and including any inline triple 140 or quad 120mm rad on the market, although a quad 120 would not line up *perfectly* the ends would stick over the edge of the bracket..however airflow would still be clean through the rad.
Cutting out your fan mounting holes would allow this case to accept any type of inline 120mm radiator..and add the flexibility to fine tune the radiator positioning as needed.
