I have brother and sister using my mac pro when I'm work. It get annoying when I come home I see it in another position where I left it before. It either got push back, reverse, or somewhere else. I want to know if there is anything I can put on the Mac Pro bottom legs to protect it from scratch? The Mac Pro weight a tons, so it will get scratch if this keep happening. I was wondering if they sell anything out there that I can put on the Mac Pro bottom leg to help it stay protected, like a soft cushion? Thanks!
