Need help with upgrade

This my rig:



I am planning to upgrade. And I am not 100% sure what to do.

What I was thinking was to add a 240 rad in the bottom, by cutting with a dremel. So I can have 2 seperate loops.

Hardware:
e760 EK-WB
I7-920 Swiftech-WB
5870 EK-WB
Dominator ram
800D corsair

I am using 1/2" ID, 3/4" OD tubing.
Radiator: RX 360 from XSPC
D5 pump
some bitspower and some phobya fittings.

Questions:

1) For 2 loops. What reservoir/pump solution do you think would be the most efficient and also look good? Maybe a dual EK top, with 2 EK reservoirs on top, to sit in the bottom right corner?

2) Should I buy more fittings so I can have all in Bitspower? (Both for looks and performance)

3) Are there any additive that can make my water (distilled) ghost white color? [I do not plan on buying a complete finished liquid. I want to use distilled water]

4) same as question 3, But with purple color. Like vladtheimpalor had on his build, if you remember.

5) Change my CPU WB to an EK HF?

6) Do you have any overall upgrades that could increase the total looks of my rig? Just give me a list of everything you can think of!

Thank you so much for helping me out.
I will be traveling over to the US this summer, to enjoy CA and also buy some water cooling stuff for my lovely hobby!

What do you think of the dual loop solution EK has for D5 pumps?
The EK dual loop top. was thinking of mounting 1 reservoir from EK on top of that, for each pump, ofc having the loops seperate.

What color would you change the tubes to? Black? :)

Originally posted by FR3SHM3AT Not black Put some color on all that white. But man still gorgeous setup. Fr3shm3at

What do you mean man? I want some suggestions! I am actually planning on buying new tubes! Got any ideas? :)

I was thinking of getting an EK res, two tall ones, and having purple dye in it. :)

i think purple and white would look killer.
