Amazon advertises these units to "work and look like new".  I have purchased many renewed or refurbished computers over the years, and have never seen a computer look like this one.  It was all scratched up, dirty on the outside and had some globs of sticky residue on it.  I almost sent it back before even plugging it in.  But, I figured it was a desktop unit that wasn't going to be visible, so if it works, I guess I can live with the appearance.  Despite it's appearance, it worked fine, came with new keyboard and mouse and was well-packed.  Not a bad unit for the money.  Set your expectations low, and you won't be disappointed!
