Hi, I just got a new PC case: "Nexus Breeze 500 Watt Silent PC Case" I have applied reasonable force to open on various parts without any indication I am using the right method to open it. I have about finished reading the Manual for my new "ASUS P5B Premium Vista Edition" which looks even better than my existing "ASUS P5AD2-E Premium" and want to put my new computer together. I do not wish to damage this new very quiet case. TIA
