Hello all, I've tried contacting support a couple of times and i've not gotten a response. I purchase a used Tower 900 for my son's first gaming system build and at first glance, everything looked great with the case. I have since discovered that it is missing the bracket for the power supply and all of the rubber grommets that are used to pass cables or water cooling tubing through. How do I go about ordering those parts as a online search has proven to be a bust lol :). Thank you for your help. Hakan
