Right of the box I noticed dust balls inside the case.  It looked like a superficial cleaning.  When trying to boot the machine for the first time I received "no boot device found" on the monitor.  The machine did not have an operating system installed.  Also the Operating System Code Tag on the machine had a part of the code covered by what looked like the scratch off coverings on lotto tickets.  Why should I have to scratch off a portion of the code possibly damaging the underlying information for a machine I bought and paid for?
