Water cooling help

[supcalafreakinawesome]

I really want to water cool my computer but I am quite confused. So i want it all to be in a Phanteks Enthoo Primo case and im going to be using a ASUS Z87 Deluxe Motherboard. I'm confused on what to do if i want to add in water cooling to my gpu, I am planning on using a XSPC RayStorm D5 Photon AX240 Water Cooling Kit and I also want to cool a Radeon R9 290X with a Aquacomputer Kryographics Radeon R9 290/290X Acrylic Glass as the gpu block. I have four main questions with the water cooling kit.
.will it be able to cool a gpu as well as a cpu
.could it cool a dual gpu
.will it fit in my case
.how will i drain my system?
Need advise as soon as possible!!!!!!!!!

Well obviously but I'm talking bout the water cooling system not the cpu. I know you have to put the cpu in but i need to know if what i have is enough to cool a cpu and gpu withought having to buy a bigger radiator.

woops I was meant to say that to Floydms I am new to this website
