Remove case


Recieved my Cetus and the extruder motor was DOA, doesnt move at all.. I've checked all the cable connections on top, but I would like to see how it looks inside the printer, if some cable might have unplugged during shipping... 
Before I start to remove all the screws, what screws should be removed to take a way the black casing? 

Best Regards Patrik

I removed the silver ones, and I was right! 
The cable was attached as it should on the mainboard though, so I gueess I have to wait for support to answer my email and sent me a new stepper card?
