This is the second "refurbished" PC I have purchased and had to return, FYI. The outside of the unit is pretty clean, but the first glaring issue I noticed is that the plastic front top cover is missing, leaving exposed, sharp metal edges. I can imagine those metal edges get hot when the machine is running.I got curious and decided to open it up, and surprise! The hard drive is nowhere to be found. This is really ridiculous. Amazon's refurb department is trash if they let this kind of mistake slip through.Anyway, I will not be purchasing another PC (refurb or otherwise) from Amazon, because I am tired of repacking defective items, and visiting UPS drop-off locations. I am done!
