I expected that referbished meant back to almost factory standards. Though everything worked, I was surprised that the power supply that I was sent had an adapter to allow it to plug into this machine -- clearly it wasn't a power supply meant for this device originally. Also the fan was quite loud -- in the way that it sounded like it did not have a lot of life left in it. And I was mildly disappointed that the WiFi dongle that came with it seemed to only work on 2GHz frequencies -- if it has to be a dongle, at least give me a modern one.As I said, it worked... no DOA or anything. But I was dissatisfied enough that I decided to send it back... though I can imagine it might work well for a lot of people.
