I just recently received my Alienware X51 today. As I take out the computer, there's something loose inside it. So I opened it up, I found these two pieces totally disconnected from the hardware. I don't know where are they from and what they do. But I'm pretty sure Purolator handled my package pretty bad...they might dropped it.
Anyhow, I've included a picture of these small parts. Please check it out and let me know whether or not I should be worrying.
