I just got a new pc case, NZXT M59, and I don't know if I'm doing anything wrong or not. I looked at the online manual to see how to open the other side of the case for the cable management and it wouldn't budge. I took out the screws on both sides. The side where you put the pc components was a cinch to slide off but the other side seems stuck and won't budge even putting under force to open it up. I tried sliding it out the same way as the other side and then lifting but it won't budge. Help is appreciated.
