Just a heads up on one thing to try regarding whining ,ive been testing all day today with a new psu and the bitfenix merc alpha case
first i tested a 5770 and could hear the whining only through the front panel headphones,swapped to a 5870 same thing,did fresh clean install of windows,same whining could be heard,switched psu,same whining could also hear
it screech when i moved the mouse pointer across the screen making me think it was gpu related
at this point in time i disconnected the front panel usb the motherboard and voila!!! as quiet as a mouse
so if your having similar issues id suggest you try this and see if it fixes things or you
p.s it looks to me that bitfenix have mounted the usb sockets to close to the headphone socket or not shielded it adequately hence the interference noise
