I had none of the negative issues that some people have had with this PC.  Well maybe two small issues, one with the initial opening of the side panel.  It took me about ten minutes to figure out why it was stuck and now it opens and closes with no problem (there was a metal tab inside of the lever that was hanging up, I was able to use a small jeweler's screw driver to bend it so that it wasn't hanging up.  the other issue was where I took the advice that one person mentioned about not using a coin to get the Windows 10 product key, I lightly scratched the surface, it was a little hard to see one of the letters clearly but I was able to see enough to try a couple of different values to get to the correct one.  If a value wasn't one of the accepted Microsoft values it wouldn't let you type it in.  Those plus a couple of small scratches were minor.  I have purchased refurbished monitors that had more scratches on them but have been functioning for about three years now with no problem.After I fired it up I applied all updates and cloned the hard drive to a larger hard drive and haven't had any problems with it.  I plan on adding another 8 GBs next month.
