The iMac arrived in pristine condition, and I was able to update it to the newest OS immediately (something I was worried about with and older Mac). there was nothing of note on the chassis. Of damage, the only thing I could mention external or otherwise is there was a small sticker on it, which I was able to easily peal off. The keyboard was brand new and the Magic Mouse seemed to be, if not new, very lightly used. Both were of the latest generation and Bluetooth. I know some other reviewers had problems with this company/product; and that almost turned me away in favor of a newer, more expensive, model; I am so glad I didn’t do this, the computer is fast, and I got a device which fits my needs perfectly at a drastically reduced price. I would recommend this to anyone who is looking to use it for normal use (I usually have 10+ windows open at once on my desktop and 10 times as many safari tabs and it doesn’t slow it down at all). Everyday use that is, if you use it in the conventional sense of the word (would not recommend for gamers, etc.)*NOTE:One thing that I wish someone had told me before I purchased this was that, IT CAN NOT BE USED AS AN EXTERNAL MONITOR, at least not without a $350+ device such as the Elgato 60s+. This would not have been a dealbreaker for me, and I would have still bought the device knowing this, but this could be a necessity for some users and a shortcoming which is not well advertised.
