600C W/C Build, advice for parts & looks

So I'm planning on moving my rig into a new case- the 600C.

A lot of the reason is because it's inverted and the rest is because the 540 takes up half my desk.

So, I'm planning on color co-ordinating this- specifically, white/black

I've seen a few black exterior with white internal builds and I'm really falling for it. I've wanted to finally build something unique for god knows how long (been building for 5 years, since I was 13) but never been able to afford it.

Parts list so far:

1x280GTS Black Ice radiators, 1x 140GTS (maybe another 280?)

XSPC Raystorm & Single-bay DDC Res- 600Lp/h

EK MSI R9 390 block (only one of its type)

And as mentioned, the Corsair 600C

Stuff I need:

Res- for looks only in the front, possibly covering the black cable gromits

Fans? Need some which can take low rpm, while still being somewhat efficient and not £20($25) a fan.

Pwm splitter or controller?

Various other bits for watercooling (fittings, tubing, coolant)

1. Can it work? Will the slight tint of the exterior black on the 600c ruin the black/white colour scheme?

2. Enough rads? Hoping to run fans at low rpm. Minor overclocking but nothing over the top- my 6700k can barely handle 4.2GHz, and my gpu is just as reluctant.

3.Braided cables? Could white cables suit a black board? (will be covering/taking off the red bits)

4.Anything else worthy of mention? Have I mucked up at all??

Apologies for all the questions but this'll be a huge expense for me- I've always wanted to make something I'm truly proud of. Churning out black/red pcs for mates gets a bit boring after a while.

Thanks & have a great evening,

Kai

P.S: anyone got an old msi 390 8gb lying around? Might as well make it a pair.
