Cats will be cats. No way they weren't going to jump up on the case and power off the PC in the middle of a raid.
A little TinkerCad and some precisely deposited molten plastic and there you have it. All night cat-safe raiding. (This statement is for marketing purposes only and no warranty, express or implied, is provided by the designer. Use at your own risk)
The model has a portal for cleaver humans to access the power button and a slot to ensure there is no obstruction of any LED goodness.
Currently designed to fit a Fractal Design 7. I am learning OpenSCAD and hope to have a model added so that it can be modified to protect a wider range of power buttons from a wider range of pets.
The author marked this model as their own original creation.
