Buy a Lian-Li PC6070B if you really want quiet -

Soooo nice and so easy to work with. Silent padding in the chassis, so much better made than the plastic P180 which in my opinion gets so many props only because people get stuck with it and insist they love it..
From all accounts, the included dampening material that somes with the Lian Li's are useless.
re: P180. Plastic will make less noise than metal from vibrations in the case. The amount of the mass in the case helps with this. Pure aluminum is going to resonate more easily due to the lower amount of mass/weight vs. Pure steel or the al/steel/al setup of the P180.
The middle fan in the bottom of the PSU chamber is used to blow air directly onto the PSU. This is absolutely necessary for passive PSUs, and the amount of air from a 120mm fan blowing on a PSU with an 80mm fan will provide more cooling as more air is reaching it due to the proximity from the larger fan. This in turn should keep the PSU ramping up from the otherwise higher temps without this fan. The fan in the middle also pulls air across the harddrives, keeping them cool as well.
The P180 is NOT shoddily made. The door design is bad, though they've apparently released a newer version in Japan that fixes this problem (instead of just being aluminum/steel, it's now al/steel/al like the rest of the case, apparently providing better support).
The P180 is an overrated case; even Mike Chin, who helped design the case has stated it as not being perfect, listing both execution and design flaws in the final product. Additionally, most cases don't come with a front fan anyway. The PSU chamber is separated from the rest of the case to keep both the PSU and the CPU cooler, and the top fan can pull more air over the CPU to keep that even cooler.
The P180 is not a perfect case, I've never understood the hype for it, truthfully, but saying it's shoddily made and complaining about the lack of a front fan is unwarranted.
