Hello everyone, wow it's been a very long time since I last posted 3 years now... I'm happy to be back though. Here's the deal, I've been looking for tubs for a rack project I'm working on and found this sterilite ones that are basically the same size as the cb70, what worries me is I don't really know how durable or resistant those tubs are heat-wise. Any opinions, or suggestions anything helps thanks!! http://www.walmart.com/catalog/produ...ct_id=10401039
