I purchased the 3040 micro and could not be happier. The computer looks brand new, the only evidence that my 3040 was used was a very small amount of dust inside the fan housing. Warning: be very careful who you buy from. I purchased from (Prime Time Buys) who is no longer listed on this item. Look at the ratings of the seller before you buy and you will come out with a great product at a great price. Complaints with all refurbished items come from low rated sellers.
