I feel ya. I have a dog and three cats, but so far have not had an issue with hair or cable chewing. The frame is essentially just a kit of 2020 extruded aluminum t-slot rails with connectors. If I were to do this again, I would probably not go with a kit and instead just buy the rails and connectors I need for my specific motherboard/components. Also, any extra rails/connectors you get could go toward a DIY 3D printing frame (that’s my next project)!
I regularly quote: “I was BORN on that TABLE!” And “Straight out of my BODY and onto your PLATE!”
