I bought the same cabinet from another forum a few months back. It didn't hold my larger, bent pipes well, so I cut out the holes into u-shapes. That lets the pipes be a little loose, so I just picked up some thin, elastic band to put across each rack, that works great. I paid $100 for mine, probably a little high (but it funded health care for the seller, so a good cause). That is a nice setup you have!
