Even just looking at them is a problem. The main computer is held in place with two screws? Posts? and the weight of the machine can make the acrylic crack. I have two of them, but I store them upside down. I 3d printer some support braces, but my printer at the time sucked so they weren’t a perfect fit and it took a ton of work to file them down to the right size to fit, but not fall out immediately.
