Fractal Design Celsius S24 Vandkøling

Chose a Fractal Design Celsius S24 Hydro Cooler as part of a gaming computer build for my grandson. First class cooler, easy installation for my first build, but I was following instructions in a magazine article which failed to mention that when the radiator is installed in the roof of the case it obstructs the 5.25 bays so no room for an optical disk drive. So what? you might say, well several of the other component drivers come on disks, I had to temporally rig a optical drive onto the mother board from outside the case, it worked, but something to keep in mind.
