Assuming you are talking about a HAF X, if not then disregard.
A page or two earlier I posted a link to my build photos on Imgur. I have a 240 up top, a 140 mounted off the rear of the case and a 240 in the bottom. The water passes thru the 240, into the CPU, thru the 140, into the GPU's and then thru the second 240 before it gets back into the res. If you are worried about room, it's a good set up. The 140 at the back just requires a few rubber washers in between the rad and the case to make up the clearance of the protruding fan area. Then, the fan on the inside with a few longer than normal screws, thru the case, thru the rubber washers (2 per screw hole) into the rad. You can use the pre cut holes directly above for tubing.
EDIT: the same concept would probably work with the other cases, just match rad size to rear fan size.
