Have you considered a H60 or similar?
What components have you got fitted in the case?
tbh i looked at this, i could fit it at front, but i could also mod my case and fit it externally on top![]()
Would it not spoil the look fo the case stuck on top?
If it could be rigged at the front, internally, it should keep your q6600 nice and frosty considering the confined space - probably one of the few occasions where an all-in-one water solution is better than a quality air alternative as it's expelling the heat directly out of a confined space (if you choose to vent rather than draw air into the case).
