We have bought many of these for resale - I have had a computer company for 38 years. The hard drives all of the refurbishing companies are using lately are junk - either BTO or Kingfast. The failure rate I have been seeing is at least 33%. However, the computers themselves are good deals and everything else about them works fine. I have been purchasing Samsung SSD drives (the best!) and replacing the junk hard drives immediately before we deliver them to customers. It is easy to change the SSD drives out. You will have to clone the old drive or just install windows on the new one (no cost to download the Windows 10 install). For the money you will end up with a great, stable machine.
