U shud install the cpu before installing the mobo to the case. Else u will bend the mobo like you did. If you don't want to take out the mobo, then check if you have screwed in all the srews that hold the motherboard to the case.
And if u are reinstalling the heatsink on the processor, apply some thermal paste or thermal pad before doing so.
