The BIX 2 is a dual 120mm fan radiator. He would not be able to fit that in the front of his case. The only feasable place to fit that internally would be in the top squeezed between the 5.25" bays. He would have to mod his case by cutting 2 blowholes in the top for the fans. My impression is that he doesn't want to mod because he is getting a case with a 120mm fan in the front already.
I'm not sure of the dimensions, but it looks like you could fit a Chevette heater core or a D-tek JR-120 (same thing, but an inch shorter) in the front if you took out the hard drive rack. That would still require modding though. You would probably need to drill out rivets to remove the metal structure on the floor of the case that the HDD rack snaps onto. Then you could mount your hard drive in a 5.25" bay. If you have several hard drives this method isn't the best.
The other option is to cut a blowhole in the top of your case between the 5.25" bays and your power supply. That method works, but air in the water will go straight to the radiator if you don't bleed it completely beforehand. Also the top of the case isn't the best place for cool air intake.
To the subject of which radiator. I would get a heater core or a D-tek JR-120 (it's a painted heatercore with barbs pre-installed). Computer specific radiators are expensive, and in the case of the Black Ice series don't perform as well as a heatercore. The only real advantage comp specific rads have is that they are usually a bit smaller than a heatercore.
