I have my fingers crossed and hope it works out for you. I also thought at first it wouldn't be a problem and had my rig planned out this way. It might have worked with a lot of force and with the tubes pressing against the top fans the whole time. Check out the pic, the part where the tubes come out of the radiator are on the same height as the top fans and the tubes are way too stiff to bend them this angle. I mean not without a lot of force on them all the time.
I really wonder why it's so hard for corsair to just give you a few extra centimeters so you can install everything. I love the look of the case, but the cable managment and installation was a huge pain in the a.
