well, the push or pull debate usually leads to ppl saying pull, to you can put the fan in front of the radiator. as for mounting it, the black-ice manufacturer's website shows a good installation guide when putting it on an 80mm fan mount, using some screws and a 120mm fan guard (all you do is screw the 120mm fan guard onto the case using the holes there already (screw into the smaller rings), but place 4 screws facing outwards in the holes meant for a 120mm fan), then once the fan guard is on the case, just screw on the radiator. now, thats kinda the easy way out i guess, but otherwise you'll need to cut out a chunk of case to attatch the radiator (prefferably at the top)... use a dremel or a hole saw, cut out a 120mm hole, drill out the appropriately spaced-out holes and then screw on the radiator from the inside and voila!
