A friend in need

[MajoVoodoo]

Hey! I have a three year old Acer predator G3-605, and I recently thought about changing the thermal compound and the fan - because the temps got really high - So I bought an "Arctic Freezer i11" and I can't get it into my pc, because I can't get the back panel open ( I do have access to the motherboard, but I need to access the backside to install a part so the screws go all the way) and I have basically no clue on how to open it. Any help appreciated!
