There are a couple of pics in my album showing how I modded my C650D. I have my rear rad outside with tubing coming through the wall. My top rad is inside with the fans outside.
And if you plan to stick with your first idea - its fine, tubing length isn't as critical as the number of 90 degree fittings and waterblocks.
Thanks. At this point, I'm liking the mounting it out the back idea. Lots less tubing without having to cut up the case. I'll just have to bleed the radiator before mounting it fully--let it lay back, bleed it, fold it up and secure. I saw someone post a diagram of doing just that.
Also, if getting the tube to the far side of the rad out the back is hard, I could try to take it out a PCI port back there. Though... 3/4" tubing might be too big without a little "help".
