The unit appears new except for a tiny paint nick on the back edge which you would not notice. It came equipped with 16gb of ram, a 2tb hard drive, and a dvd r/w drive, as well as a wired keyboard and mouse. It fully passed diagnostics, even the long mode.I asked a question of the seller and it was answered within a short time.As far as refurbished goes, the unit is 6 years old but looks new. The hard drive is a Dell/HGST with 9 years of spin time on it, but no sectors needed to be corrected, so perhaps it will last another 9 years. Did Dell build the original unit with a 5 year old drive? The keyboard was new but extremely cheap, I had to check any passwords I typed in because it tended to add extra characters. Perhaps just omit the keyboard?Final result: I put an SSD in it and my wife is pleased with the extra performance from the Core i7 and 16gb of memory.
