very stupid question, but how do i install the  XIGMATEK ACK-I7751 Retention Bracket?
 
it goes under the motherboard? then that make the motherboard stretch out and doesnt lie flat anymore?  
when i screw the motherboard, it's goign to create a lot of tension?  am using rc690 case,  
 
 
please show me how to install  XIGMATEK ACK-I7751 Retention Bracket.  
 
thanks

bump......
 
the motherboard bends as i put the backplate on, it doesnt look so good,  
 
it doesn't lie flat, bending, is it supposed to be like that?
 
any suggestion? thx
