So I just received this https://www.cyberpowerpc.com/system/Gaming-Instant-Ship-GML-99544 and I’m trying to add my drives and switch the cooler but I cannot pull the back side panel off. It seems as though cyber power bolted or screwed it directly onto the case. I’m pretty sure the case is a phanteks p300. Here’s a pic of the weird screws used to secure the side panel.
