Watercooling / Air flow question

So I'm still planning my watercooling system, have most of the parts ready to go. However, I'm starting to realize that the way I had planned to position my heatercore poses some interesting problems for air flow.

I had planned it like this, with the air flow going through the shroud and heatercore, and then out the front "intake".

So first off, am I wrong in putting the shroud/fan on that side of the radiator?

Either way, I don't want to have the fan blowing hot air through my case,and I think it will exit fine out the front. Should I switch the rear fan from blowing out to blowing air in, and make the rear the intake and the front the outtake?

Or am I just stupid for trying to fit the heatercore inside my case, and I should break down and put it outside?

Tubing is 3/8" id tygon.

Pic is crude I know, but I'm not going to waste my time diagramming it in Autocad.

Thanks for any help and suggestions.

Fan and shroud: position it so that the fan pulls air through the rad. Pulling is usuually better by a degree or so vs. pushing.

Blowing 'hot' air into the case isn't big deal--all that heat was in your case before, right? But if you want it to blow out the front, put in a blowhole on the side of case. Well, more of a suck-hole really. Position you new hole between rad-fan and vid card--the air coming in will preserve the natural case airflow pattern and will feed cool air to the rad.

Yeah that sounds like a decent idea... and yes, I was going to put the fan so it would be pulling the air, rather than pushing. If i did add the blowhole, would I still leave the case fan in the back how it is, or should I reverse that?
 
I'd leave the fan in the rear and keep it exhausting; just to make sure there's enough airflow over the mobo keep stuff cool.
