If the side was left off then even better. I have been through this before and ended up leaving the side off, this was using a TEC though as it is very important to get these steps as correct as you can.
alright, just to clarify. the heater core will be on the outside of my case mounted ont he back using a swiftech radbox ver.2
so, since the rear of my case has the raised fan grills I'm going to use standoffs inbetween the rear of the case and the radbox. Then the radbox will be connected to the top fan, which will be connected to the shroud, and then the heater core. So, if the standoffs are about 1/2" and the radbox itself is about 1" and so is the fan, and the shround 3/4" the heater core will be mounted about 3 1/4" off the rear of the case.
so most of the air will be coming from outside the case, it is entirely possible that some air will be drawn from inside the case, but the majority of the air going through the heater core will be external and thus cooler.
I hope this clears things up... and it works. The radbox was designed to work with traditional radiators, single double or tripple. I don't know how heavy they are, but if the heater core is much heavier it may not work.
