For the last couple of months I've been messing with getting this thing removed in between other work and finally feel it's time to ask for help. I've removed the screws, but it still feels like something is holding it in. Do the top latches somehow hold this on? Hidden screw, maybe? What's the deal? Thanks.

Clamps for the top must be removed. Two m6 bolts accessed from underneath. Then there are screws . Sometimes hard to find with the screwdriver tip

AHA!!! So it is the clamps... Thanks
