Also beware that if you really need 11 bays, the structural integrity of the case will be from the drives, not the case which is a bit on the thin side. Why someone will spend hundreds on drives but not $30 more on a case is beyond me.
But, so far as cheap cases go, there's a certain minimum price under which it take a lot of time or bulk purchases to keep a supply, so yeah, it's a deal @ under $35 delivered except for having to buy another PSU.
