Well, that's sad news. They're just sending out replacements without recalling and resolving the situation. 
 
I know this is about getting what we've paid for, but honestly... looks SO much better with a controllable RGB led strip there..
 
EDIT:
 
 I have been waiting for my replacement for a while, so I pinged customer support, they did give me this response:
 
We are currently in the process of obtaining the replacement LED strips from the manufacturer and will be shipping them out soon as we do have your information on file. I do apologize for any inconveniences this may cause. If you have any concerns or further questions you may contact our Support Team at [link=tel:888-881-3842]888-881-3842[/link] who are available 24/7.
 
 
Perhaps this means these are revised/better strips? Sorry to those that already got theirs with the same issues.

One thing for sure, they will get it worked out. I am good with the white LED as that is the theme of my build but RGB would have been nice however, there is no way to control it with the case alone. The Asus RVE10 had a RGB header on it but the x99 FTW K does not. I am using a Corsair Commander Mini that has RGB LED control but I just want the light white anyways.
 
When I compare the old yellowed strip to the new yellowing strip, they look to be the same. It almost looks as if the plastic is being burned making it brown. This is causing the light to get a yellow tint to it.

Well, surprise surprise; Booted up today and all but one of the LED`s on the strip are now Yellow :(. Guess its time to call support. 

Here are mine  will be contacting support.
This photo was taken like a week ago, didn't have time to post but checked today all yellow.
They might as well send out 12 new strips...one for every month!
The plastic is like a dust magnet BTW.


 
 

I just received my case today. I want to replace the LED strip with a RGB but I couldn't remove the plastic piece that holds the strip in. Can some one please explain to me how to remove it before I brake something.

Three screws behind the filter

A week later and 7 more LEDs are yellow, it's like 1 a day is turning yellow.  Over a 1/3 of my LEDs are yellow now :(

All of mine are yellow, but they seem to have settled down now. I'll probably try for replacement later in the month.

All of mine are yellow on the second strip. I will be going aftermarket not sure what I will get yet though.

Conclusion time!
 

 
it is how the LED is mounted inside that black plastic housing and tucked into a tiny corner completely restricted from any airflow that is making LED's brown. i just had my CableMod UV LED's brown, above pic. so take it from me, do not put an led strip there.
