Is it possible to replace the DVD drive with a Blu-Ray drive in a Xbox ?

I would like to replace the DVD drive in my Xbox with an internal Blu-ray.
Would there be problems playing Xbox games?
Blu-Ray will be able to play after installation?

You can not put a Blu-Ray on Xbox 360, unless you open it and install it manually. Microsoft does not offer this option yet. Opening your 360 will void the warranty if you break it while installing the drive you are screwed.
