Very fast! I use it for school and can run some pretty demanding software on it occasionally, it runs smooth ; If it was refurbished I couldn't tell. It came like brand new, clear plastic still stuck on the computer

Kind of an odd noise on start up, but thats not worth a complaint ; Nothing

Arrived fast, quiet running, has been working good since I bought it over a month ago. Little signs of wear and tear

Bios simple and dated, unable to do any features (such as over clocking). Not real upgradeable
