The controller has failed and the owner has a new one in-use. I wanted to take a peek inside. I removed all 8 case screws and have gently to moderately tried to separate the top plastic half from the bottom Aluminum half but noting budges. I lightly tried tapping a sharp chisel into one end and I can see a sliver of separation in the middle but no movement at the edges. I also tried inserting a punch through each screw hold to strike the aluminum case below and this also has no effect. I've checked under the labels for hidden screws and didn't see any. The top plastic case looks like it fits right over the 5 input/output terminals so I don't think they are an issue. Is this case glued and or a press fit?
