All those exposed fan holes would surely be a way for noise to escape. On my P183 I find the rear 700rpm-850rpm Apache is the loudest fan to me ears as it has a totally unrestricted noise escape path.
The HAF 932 of course has a big gaping fan hole at the front, one at the side and one at the rear and the least said about the top the better.
I'm sure it'll cool better than the P182 with dual cards in there Tommy but I'm not wholly convinced you'll find it quieter.
The trouble with looking at reviews and what not for cases is that people's idea of noisy can be very different to yours or mine. Saying that though I did find the stock P183 far too noisy, even with low fan, and that's marketed as a noise dampened case.
I've often thought I might like a different case with larger fans up front but to be honest I don't have any heat issues with the P183 with slow fan speed. Things get a little warm inside and case temp is a good few degrees above ambient but nothing is really hotter than it can cope with. If I were to swap I might be tempted by one of those Raven RV03 cases. I quite like the rotation idea and the fact that there is a fan slot right next to where my graphics card is located, it could do with being a tad lower but I'm sure a 114mm holesaw would help with that.
