I have only recently started visiting this site on a regular basis because of a pending purchase - I wanted to know when new hardware was coming out. So consider me a newbie.
I typically don't register at sites I visit but I was compelled to after reading the post by rw3:
"Believe me now....I'm so good at taking Apple stuff out of the packaging and apart that I took my Mini back today and they said, "You didn't even turn it on." LOL!!!"
I am saddened that there are people who consider this type of behavior acceptable. Unless I misunderstood the post, rw3 bought a machine, took it home, took the machine completely apart, then put it back together and returned it to get his money back. The fact that you took the effort to make it look like it had not been opened indicates to me that you had no intentions of keeping it. Don't even bother with "after I took it apart and looked inside I didn't like what I saw so I returned it"; otherwise, you would have told them that when you returned it.
For those who consider this 'no harm done'. Would *you* buy the machine if the salesperson told you the machine had been dismantled and put back together?
Come on dude! Walk a higher path.
