This has been common knowledge for years, and I've even stated it many times on these forums. It isn't just 1 or 2 cases of it, it's enough cases that NewEgg blames it on "Customer Induced Damage", that I simply cannot recommend them.
Amazon on the other hand.... replacement sent out normally next day shipping in my experience.
I've seen this happen only once to myself on one of my last motherboard purchases from NewEgg (thank god... Amazon tends to have better prices and shipping options anyway), but numerous times to friends. NewEgg even tried to double charge one of my friends for a replacement board they had already sent out before telling him that it will not be covered by NewEgg's return policy on motherboards.
They have lost the majority of my business long ago and I very rarely and seldom order anything from them. It's been about 5years since I washed my hands of NewEgg and things have been dandy. I only use NewEgg as a research tool now, nothing more.
Some more insight on some quick posts that popped up on google regarding it:

I'm not saying you may not find a sympathetic NewEgg rep to help you with it if you come across this issue on a new board, but just keep in mind that NewEgg HAS screwed over MANY many customers over the years with this practice.
