I'm looking for a rackmount case for my firewall at home here. I have a custom made rack that's basically a 2 post rack. I'm wondering if this http://www.newegg.ca/Product/Product.aspx?Item=N82E16811219032 case would be able to be mounted by just it's ears and be fine that? It seems kind of deep and would have a lot of weight in the back of it...
