Its a good rig, nothing wrong with it.
Only thing I'd change is the SSD, get a Samsung 830 instead. Better performance than that Intel 330.
There are sound scales somewhere that will tell you how loud that is in comparison to a sound you will normally hear. Though considering that a silent room is ~20 dba, don't think its that loud. Also that 36 dba is when the fan is spinning full throttle, which likely wont ever happen.http://www.gcaudio.com/resources/howtos/loudness.html
Its apparently just above the ambient sound of a quiet library...
7950 all the way.
EDIT: Just noticed the single channel memory, you will want to change that to dual.http://www.newegg.com/Product/Product.aspx?Item=N82E16820233379
