When I first received i, I noticed no wifi adapter or bluetooth dongle included. I then opened it up and saw an empty RAM slot. But the dongle and adapter were already plugged in an |I had the right amount of RAM. I plugged in and it worked well. After checking it was fine I moved it to my bedroom. I laid it on it's side and it turned off. But it's working fine now. The optical drive's tray is, for lack of a better word, limp. After having it ejected it doesn't open all the way and have to press a disk into it for it to stay. But other than those hiccups, it's a really impressive computer for the price.
