I ordered Ready Rails from Dell last week.  I have a PowerEdge R200 server and actually ordered 2 sets since I have a few of those servers.  The rails they sent were Item #330-6301 or the box says PN #0C597M.  These don't seem to be for the R200 server as the knobs on the server are too large for the rails to attach too, they line up perfect, but it just seems like it's wrong.  My dell rep checked and was told these are the right ones, just wondering if anyone knows of a different set of rails that will work for this server?
