I think it varies from person to person on the the RMA techs/customer service at hand @ the EGG. I bought a motherboard and the first 2 dimms didn't work. I had the blinky red lights preventing the PC to boot. Pulled the PC apart to re-seat the CPU and found 1 pin on the right a little different. It appear as if it was half extend with a crease. I took pictures of my whole unboxing so I revisited them and noticed a little shiny pin prior to even touching the socket with my gorilla hands. I told them about it and unless you actually physically damaged the pins because I never have there is IMO something fishy in the supply chain after reading so much on this topic. I am sure half are user inflicted which put such horrid policies in place to begin with. These motherboards do come defective and that's a fact rather they believe it or not it is.
Got the email stating they found 1 pin or pins under a magnified glass which would fall under their non return policy which I knew they would, but they took care of me this time.
I actually have bought a zillion mobo's and PC parts from there so maybe I have some good standing and the the board was replaced with an exemption. Waiting on the return now hopefully no more issues so I can play with my new toys. Turn around time from when I sent it to to the time it will return with the RMA hold will be exactly 1 week. Not to shabby IMO. I also exchanged the Intel I7 4770k just in case it was damaged by the socket.
