System Placement Question

I recently moved into a bachelor/studio apartment and I'm trying to figure out how to organize the room. One option is to assemble the system against the back wall and have the speakers fire down the length of the room. While I think this option is best, there is a radiator against the back wall in the center. Would assembling the system in close proximity to the radiator be a big 'no-no'?

Some of my initial concerns are that the heat generated by the radiator might warm the speakers too much, resulting in floppy bass. Moreover, I'm concerned that the heat may harm the longevity of my amp/CD player (both are NAIM). Does anyone have any experience with this?
