hiya
Last year I set up my P182 Q6600 setup.
I felt the TriCool fans were a little low on airflow at low speed and too noisy at med and loud at high speed.
(try them out though, they are pretty good and can be upgraded any time)
I bought a bunch of Sharkoon fans to replace them as appeared to have very good reviews and tests --- Their airflow might be good but the "dimples" (like on a golf ball) caused an annoying noise that maybe a DB meter does not register as loud, but was an irritating "mechanical" airflow noise to me that grated on my senses
I have those running through a fan controller - still too loud
I added 7v resisters in line with the fan controller
Now is Very quiet and still has decent airflow.
There are some good fans out there now, like maybe the reasonably priced:

(without doing more than reading user opinions and seeing a blade design similar to another very good fan I have - creates smoother purring whisper as it runs compared to my Sharkoon 120's (even though maybe DB is the same))
Bear in mind when ordering a PSU that (if the 183 is the same as my 182) you will need some fairly long cables coming from it.
I have a Seasonic S12 500W Silent which will be more than enough to run your proposed system - is very quiet and reliable. (maybe now superseded by a newer model ??)
My system has:
Q6600 @ 3.6GHz
8800GT still
Xfi-Gamer Sound Card
6 HDD
Usual other nice bits
All this only draws about 265 watts under load - you really won't need a bigger PSU.
Am sure others here can recomend some other good PSU's - I can personally not mention other brands as I'm not sure which ones have long enough power cables to reach from the bottom of the case
Am very happy with mine, Good luck with yours ^^
