Alright, wanted to go ahead and order the Dark Rock, but saw the Kabuto being a 1/3 of the price it, so I'll go ahead and order that one. A few degrees worse shouldn't make difference. Just hope its not too far away from the front fan so it doesn't affect performance.
Does anyone know a heatsink (removed fans) for the cpu that is tall enough to touch thick fans like the Corsair ML120? I'm thinking of using the left front fan to cool the cpu directly with the heatsink rather than it be as an intake for the whole case.
