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)!

For my ITX build I went with this open frame so I can really customize the placement of each component and keep everything nice and compact. I’ll probably build a cover to go over this frame at some point.

Apparently it stands for Computer, I guess to distinguish them from TTRPGs. Had to Google it because they never bothered to spell out the initialized term in the article.
