Coolermaster COSMOS Build w/ Pics

[Meatpuppet]

How did you mount the rad on the top of your case? I am a comos too, and I am thinking of mounting a rad there.

Well I cut a hole big enough for the fans but not large enough to fit the radiator through. Then I grabbed a piece of aluminum and took the measurements of the width of the cavity fromed in the top when you remove the black vent piece. After that, it was just a matter of drilling a couple of fan holes (using a holesaw) and screw holes to attach the fans and radiator directly to the mounting plate. I also drilled a couple of holes at the top and bottom of the plate so I could secure it to the top of the case (I had an annoying vibration induced buzz before I screwed it down). If you have more questions after reading this and seeing the picture of the radiator plate in the original post let me know.

p.s. I almost forgot to mention that I had to cut off the middle screw down points on each side of the plastic shell, you can see one of the empty screwholes in the upper middle/right of the mounting plate picture.
