I think they called back the rgb products to change the logo because of this huge shitstorm. Hope this doesn't take too long!

This post explains every step to replace or modify the LED, that is mounted in the socket of the powerbutton of any Fractal Design Define (R2, R3 or R4) case.
If you have any questions I will gladly answer them.

The reason I did this is the pointy light the illuminated plastic socket emitts which could possibly blind the user or other persons in the room.
 

Tools you need
mid-sized crosstip screwdriver
small flat-headed screwdriver
 
Before you start
Power off your PC and disconnect the powercord or switch off the PSU.
 
Step 1: Removing the front cover
To remove the front cover simply pull on it. On the bottom side you will find an opening which you can use to do so. Please be carefull when removing it since the frontpanel is still connected.
For easy acces to the powerbutton's socket I suggest you to now disconnect all frontpanel cables and pull the front cover off of the case itself.
 
Step 2: Removing the USB-Connector-PCB
This is necessary to later pull out the socket the LED is sitting in. To remove the USB-connector-PCB undo the two screws with the mid-sized crosstip screwdriver on both sides. Then carefully pull it back a bit and then down and out.
 
Step 3: Removing the Socket of the Powerbutton and the LED
This is a critical step due to the fragility of the plastic you are about to work with.
To remove the socket undo the two screws that are fixing it into place and push it down without any tools until it stops.
It will barely move a millimeter but that is enough for now.
Now take your small flat-headed screwdriver. To prevent scratches during the next step I suggest you to wrap plastic tape around it before you go on.
 
 
If you look carefully you will notice a small gap between the front cover and the socket.
 
 
That is where you want to put your screwdriver and carefully leaver the front covers's plastic up while you push the socket down and out from above.
 
Step 4: Removing the LED from the Socket
The LED is a standart round-headed 3 mm LED with flange. It is glued in with hot-melt adhesive. To pull it out do not pull on the LED's contacts but take your screwdriver, stick it in between the socket and LED's flange and carefully leaver it out. Please take note that the actual button can be easily removed towards the top by pushing on the connector-side.
 
 
Step 5: Modding or Replacing the LED
When choosing your LED keep the following data in mind:
Voltage: 3,3 V
Diameter: 3 mm
As I stated in the beginning I am bugged by the pointy light of the LED.
To change that I use very fine grained sanding paper to matt the LED's surface.
 
 
As you can see the light is now spread more evenly.
In addition to that I also matted the powerbutton's and LED's socket. This spreads the light out more evenly over the socket's surface.
 
Step 6: Remounting the LED
The LED just slides back in. If it is too loose you should consider glueing it in.
 
Step 7: Remounting the Socket
Line the socket's front-facing fin up and slide it in until it stops. Then push the socket up using the ring around the powerbutton as a guide for its final mounting position. After that screw the two screws back in by using the crosstip screwdriver.
 
Step 8: Remounting the USB-connector-PCB
Line the USB-connectors up and slide them up until the PCB finds it's place into it's mounting frame. Then screw the two wide-headed screws on each side back in.
 
Step 9: Remounting the front cover
Pull in all cables and simply push the front cover back on. Reconnect the cables and you are done.
 
 
Quite an improvement I would say.
