The Dell Optiplex 7101 arrived exactly as described.  Inside and outside it was clean.  I had one problem - it could not find the internal hard drive at boot up.  Bob at Tekrefurbs walked me through how to reseat the SATA connector on the SSD, and everything works fine.  Great Technical support.  I asked several questions about the refurb process - yes, they do replace the CMOS battery and thoroughly clean the CPU heat sink.  This is a frisky machine that should serve for quite a while.  It comes with a new keyboard, mouse and wireless adapter, but they are not high end accessories.
