Based on that picture you'll get the sunbeam cooler in no problems. My P5Q-Pro's northbridge is really close but i managed to get it on no problems (touches the northbridge). You can also fit it to either face the rear of the case (exhausting out the back), or facing the top of the case (exhausting out of the top if you have a top fan)
I've been checking out some Yate Loon 120mm fans (maybe the 1200RPM ones to avoid too much noise?) as well as some modders' mesh. So in total, I'm thinking of getting:
Might mount it (posh way of saying glue it) on a rubber eraser from Rymans to absorb any vibrations as it's easier than trying to screw it into the mesh. 


but then again, it WAS a bank holiday, so pros and cons.
