Processor was upgraded on the unit I bought and they did not change the sticker on the case.  Not really a problem, but had me worried something was wrong until I had it up and running and could see the true system specs.Also, mouse wheel stopped working after 3 days. Plan on replacing mouse and keyboard in the near future.Wifi adapter could not connect to my router on first floor when computer was on 2nd floor directly above it. Bought a wifi adapter with an antenna and it works great now. (Laptop always worked there)Computer has been working good for a few weeks now.  Overall happy, just be ready for possible minor issues.
