The stats and other hardware seem to be operating fine for now but the SATA drive I received with the unit was in its death bead, loud overheating. a check of the hard drive it showed was from 2009 and had some remaining data on the drive its self from its prior life. I contacted  the seller and asked for a replacement hard drive and the complied. the replacement drive arrived yesterday, its a 2011 Seagate unit that had not been formatted and contained data. I formatted the unit so I could safely check the drive. Shortly after beginning the check the hard drive died and is showing a fatal error.  I have not contacted the seller for another replacement because I don't put much faith in storing data on a unit they send me.  my advice would be to buy a comparable pc with a smaller SATA drive for cheaper and replace with a SATA drive of your size and choice. for the record the SSD drive installed works great so far. I understand that this is a bargain refurbished unit but the state of the SATA hard drives is almost unusable.
