- 360 with Scythe Slim (12mm) fans (mounted underneath) - top. Didn't have to cut any openings, just mounted it behind the 2 200mm fan holes with some sheetmetal strips (but will do some cutting for better airflow and push/pull fans). You will lose the topmost 5.25" drive bay, though (which was not an issue for me since there lives the (quite short) pump/fan controller anyway). With no cutting and just 3 fans in pull, everything closes up quite nicely. With some more cutting and slim fans in push-pull, everything should *just* clear the fan controls and power/reset switch assembly.
- 240 with slim (12mm) fans (mounted on top) - bottom. Removed the rear (2) 3.5" drive bay, and cut the bottom off the rear support for the front (5) 3.5" drive bay. Didn't lose any bays (I can still mount 5 drives in the front bay), but only have about 1/8" room between the fan and the bottom-most drive. Still, airflow seems to be ok.
- 120 with slim (12mm) fan underneath - rear. Couldn't mount the rad directly to the rear because it interferes with the cutout for the MoBo connector block, so I had to use the fan as a "spacer". Have enough room for a second slim fan there, too.
