Hi, Alienware noob so go easy on me. 

Could it be possible for me to replace an Aurora R5 motherboard with a motherboard of an Aurora R6? Considering that the case it's the same for both of them I would assume that it would be easy to just to install it.

If someone could provide me with a solid answer that would be great

edit: I should also clarify that the reason of why I want to upgrade the motherboard is so that it can support higher level processors
