As for the rad set up, link in my sig for mine. I managed to fit a sr-1 480 and rx240 in the bottom but it is a very tight fit and has messed my psu position up. If you run with the 480 with the inlet/outlet at the front of the case then I am pretty sure you can get your psu in the correct place.
Tooling wise, I also used that dremel on my tj07 (though without the flex hose bit) and it is ok, not briliant but ok. As for the sanding / polishing - maybe I am not experienced enough with a dremel but I still prefered to do the last bit of filing by hand.

I'm thinking of getting the ek res too, and also switching out my ek fittings for some bitspower ones and getting a waterblock for my 460, and getting some orange coolant, as green really doesn't fit in with my orange and black theme
