You're definitely lucky that it's running at full speed! I have to say though, I've never seen the frames bent so badly, yours had to have taken one (or more) serious blows. Even if the case had been built more sturdy, I don't see how yours could have escaped some damage, the metal behind the plastic guide rods looks like... well like:
The worst part was before I opened the box that I could listen to that clicky noise of boards going around inside the box
I even see a tiny yellow/orange thing between the fan grill and the box and I first though it was a piece of ruber that bitmain has put there for protecting the case from scrachting with the grills. When I take it on my hand I realize it was a capacitor and I assume something really bad was inside there
