mid-2015 15" rMBP flex noise?

[Studflower]

Anyone experience flexing noise from the bottom of the aluminum casing on these newer 15"?
When I lay my wrist on it to type or pick it up a certain way, I hear a "pop" or a noise like something isn't screwed on tight... Just makes the nice aluminum chassis feel cheap...
Is this common in 15" rmbps? Am I being anal?

If the 2015 is like previous iterations the pop you feel are the small plastic retaining clips that essential serve as a guide to mounting the bottom case on properly (with screws).

Unless you notice a "bulging" from somewhere on the bottom case, this is completely normal.
