[Core P5 With Water 3.0 extreme.. Help me please]

Hi guys,

 

I am building my first pc through a store over here in Australia and I am going with the Core P5 case. I have read the water 3.0 extreme wont work in the case due to the cable length, However I have been told that the Core P5 AIO bracket will remedy this? is that correct? any help will be much appreciated.

 

Thanks in advance.
