I like to use Photobucket for that reason, always crops em to 800x600 (max) lol.
That cooler looks pretty nice for boards that have the 16 lane slot one over from the left where you'll have room. Being silent must be nice, the fan on my 8800GTS is the loudest in my system.
Closed Case is lower temp, becuase the ICE fan actually allows the case to have air flow. If you open case it doesn't work as good since the air won't flow from teh vents of the shell.
