I purchased an Antec P183 from OcUK in Jan 2011 and lately my system has been crashing quite often. I don't know if this is the final cause of the issue, but I noticed that the top fan wasn't running. When I investigated further, I noticed that the fan had completely fallen apart. Is this something that Antec will replace under warranty? I haven't damaged the case or the fan in anyway but the fan blades have completely fallen off of their own accord.
