Default New motherboard, odd discharge.

First off, I love the site, the section about the difference in ALC motherboard codecs is what caught my attention to this place.
I just received the ASUS P8Z77-v pro and after inspecting the board I noticed inside the cpu socket there's a yellowish/brown/orange like substance on some of the pcb components. I cannot for the life of me identify what component this is. Is it a transistor, resistor, or other? Is this something I can clean with a toothbrush, alcohol, and patience? RMA?

Here's some pictures of what I'm talking about.

Any insight on what this is would be greatly appreciated.

This yellow stuff is the lacquer that is applied to protect PCBs. Normal stuff.

These components are ceramic capacitors.

Thank you so much! I'm not a component guru so any insight is welcome.
So I've looked into what you've said and it sounds like the lacquer in this context serves as a protective coating, yes?
This brings up another question though, if it's a protective coating why is it only clearly visible (and kind of messy looking) in those places pictured and not on all of them found on the board?

Now that I know these are capacitors, could there be a chance that this could be dielectric leakage instead of lacquer?

I also forgot to mention it was an open box item off ebay. I'm still within my 30 day return policy though.

Again thank you.
