Topcase issue - advice please

[macpo]

A few weeks ago, I had an issue with my MBP 17" trackpad. The genius swapped the topcase and now I can see that the aluminum seems to be warped. I was wondering if another repair is worth it or if I should keep the unit as it is. Since repair processes are oftenly long and that I need my computer for work, I feel a little hesitant.

I need your advice !! Here's a picture.

I'm not seeing the warping.....that looks like a scratch.....
and isn't it a unibody? how do they just replace the "topcase" like with the older macbooks?
