I want to install a DVD drive in CoolerMaster K380. Please tell me how to remove front panel of CoolerMaster K380 Mid Tower. I have tried pulling out the front pannel from down as written in the manual on page 4 & in your website. However, it does not come out. After seeing several videos online I checked for notches in the sides inside. I am able to feel the notches. However, they are so close to the edge that one can't possibly pull the notches inward nor are they getting pushed outward. Due to the 6 notches (3 DVD slots), that are outward already, I don't think the front panel can be pulled out as stated on page 4 of the manual. Thanks.
