Its not as simple as just screwing on a handle to the top of the case. The top panel has to hold the weight of the case and components.
And it looks like the front and top panel is in one complete aluminum piece and is held on to the frame with 4 screws at the top.
Also, I'm not so certain on the temps on the back of the gpu. It looks like there will be little to no airflow going to the back.
