Sound dampening cases

I was originally going to get the Fractal Design R4, but I've heard from places like Anandtech that there isn't much clearence for a H100, so a H100i is probably not going to fit. I want a quiet case, with good cooling and room for a H100i. Any suggestions would be greatly appreciated. 

Well as I suggested before, you could get a Noctua air fan which cool as godd or better. :)

Antec P280

Thom linked a good one, Antec P280 as long as you don't hit your mobo's heat sinks

Thanks for the advice! I've been researching for hours and it seems I overlooked the P280. I think I'll stick to the H100i though, I've looked around a bit and the general consensus is it's cooler. However I might use some Noctua case fans since I've heard they're very quiet and have great performance.

How well do these cool though? Now as a complete noob the cases like this(without ventilation in the side) seem like they would just be hot as hell.

A H100 should definitely fit.

He fit a 280mm rad on the front and there is juuuuust enough space for a 240mm on the top.

I got a corsair 550D which is super quiet and has the perfect mounting for the H100.
