I don't know for sure yet what my options will be as far as fan placement, but no matter my options...my 1st preference would be for the fan to blow through the heatsink towards the back of the case. I'm guessing in that case it won't fit?
GSkill Ripjaws X fits under the Scythe. If you have not bought it yet you might want to consider the Ripjaws.
GSkill Ripjaws X are on my short list of RAM I'm looking at. I don't like the red color though and the blue CL8 is too expensive right now. I could get the blue Corsair for $84.99 right now on sale, so that's why I was asking about it. It doesn't sound like it's what I'd want though with my planned heatsink.
Not sure of the height on the Corsair. If you can find it and compare it to the Ripjaws it might help. I have Ripjaws X 2 x 4GB of DDR3 1600 Cas 7-8-7-24 for exactly matching. They just fit under the Mugens fan.
