I've talked to several different apple reps and employees that told me even opening it will void it and the mac minis are not ment to be upgraded. I even showed them what the apple site says and the warranty thing and they said it the upgrades are only for made to order products meaning you can custom order a mac computer with a certain amount of ram and hard drive space.
The reps at the apple store also said that they do not upgrade mac minis. They are set as is.
