Reading about the swapping issues that you all are having from Asus reminds me of my RMA with them.
I have seriously gave up home on Asus.
Yes, they used to be my first choice when it comes to motherboard, even though, I still end up burning them, they survived long enough...until the dreaded experience I have with them at the end.

My last board died on me for no apparent reason.
PC technicians suspect it to be burnt but could not find any symptoms (swelled capacitors or burn marks).
The board just would not start up, so I sent it for RMA.
Took me 1 month+ before I got a replacement.
Now the show stars.
They told me it was new, however, one look at it and you can confirm it wasn't.
The back panel (not the plate) of the USB cover were a bit rusty.
There are plenty of bent pins.
It came in a dirty packaging bag.
Heck, there was a sticker which is almost coming off stuck to it just to tell me it was my model.
Argued but could not do anything, so had to accept the "new" board.
1 week later, the replacement board died on me.
Went back for a 2nd RMA, with some not so nice comments.
Waited for 3 weeks and they gave me a brand new board, minus the box and accessories, but at least this time, it looks new and the packging seems to be new too.

That wasn't the end of it.
A few months down the road, my Asus graphic card died.
Suspected to be due to the faulty board.
Since it was still under warranty, I went through the RMA process again.
Waited for almost 2 months, and they told me my graphic card was obsolete and did not have any spare parts so they made some repairs instead.
Collected my card and the next "best" thing you can ever imagine happened.
It died after using for one hour.
Went back the 2nd day, with lots of not that nice comments for my 2nd double claim in less than a year.
Waited for 2 weeks+ and they swapped my card with an upgraded version (from 680 to 780).
Not a new one but at least a working one.

All these experiences coupled with the one my friends had with Asus (also double claiming in RMA) have led me to lost hope completely with Asus.
My advice to Asus, buck up or lose ALL your customers.
Quality has not been as rock solid as it was.
For warranties, if you wish to offer 3 years, by all means please keep the spare parts for 3 years or more !!!

I am sorry if I have offended any of you.
I was not here to whine or complain.
It was my choice to choose Asus, and if I regret it, it was because I chose them.
I just came to share my experience after reading that some have problems with swapping their board for the B3 which made me relate back to my experience.
I have no intention whatsoever to offend any of you.
I apologize and will not be back with any irrelevant posts.
