Seems to function well overall.  However one must beware that what you see on the screen is not always what you get.  Picture indicated an internal DVD, but I actually received an external unit.  Just means another cable.  I guess this is common with rebuilds.Also 1 part was defective:  A display port/HDMI adapter, so I replaced it with a purchased cable(display port to HDMI).  Cost me an extra $30 at BB.  Vendor agreed to credit me with $20.I decided to keep it rather than take all the trouble to send it back.
