[Build Help] Recommend me a HSF for a 2500k that isn't a Hyper 212.

I have a bit more in the budget for an HSF than 25, looking in the ~50 range, would like to overclock quite a bit. The hipster in me wants to go with something better / less mainstream than a 212+, and the nerd in me wants something badass/huge. I like the design of soem of the copper Zalman's, but I read these are more for quiet than heat dispersal? I don't mind noise, as this is going in a room with a few other computers running, I just want the best performace. Thanks!

Oh, I have low-profile RAM and an Antec 300 case if that matters.
