I'm really tired of MS so I decided to buy an apple desktop. This is a great computer at a fair price fully upgrade-able to 32GB ram which I did.  And this computer is upgrade-able all the way to Big Sur although I upgraded to Catalina. Resolution is phenomenal and has 1TB drive. Came with wireless keyboard and mouse (NOT APPLE) but very nice quality. You cant go wrong and the amazon guarantee as this is a "amazon Renewed" computer.I'm not receiving any payment for this review It is a nice computer. My friend saw it and she bought one and it was again a nice computer no scratches, new looking and easy to set hers up too. These both were very clean and like new with new KB and Mouse/power cord.
