Opinions on this setup? (some questions included)

[Kogure_Chan]

So I finished building my PC about 2-3 weeks ago, and around that time I became really interested in water cooling. I've spent a lot of time on review sites, forums, and online stores, and I think I'm ready to do my first build. 
This is my rig:
 
CPU: Intel i7-4770, 3,4GHz
GPU: GeForce GTX 780, 3GB, 1020MHz
RAM: Corsair Vengance 8GB 1600MHz
MB: Gigabyte GA-Z87-HD3

PSU: Corsair CS750M
Case: Aerocool XPredator X3 (White)
 
For now I'm running with air cooling only, but as I said, I'll be switching to water cooling pretty soon. Here are the parts I want. As you can probably see, the budget isn't really a problem. I'll spend about €650 ($880).
Any opinions/experiences regarding these parts that you think are worth sharing?
 
Pump: Alphacool VPP655 http://frozencpu.com/products/13147/
Pretty much standard D5. Model with speed control. Though I'm not sure about the top. Either EK-D5 X-TOP or Alphacool HF D5 TOP. Do you guys recommend either one? Or maybe something completely different?

 

 

 

Res: FrozenQ Liquid Fusion V Series 400mm - Blue http://frozencpu.com/products/10952/
Just because it looks really f****** badass (not sure if I'm allowed to swear here  ). I will mount it externally together with the rad.

 

 

 

 

CPU block: Alphacool NexXxoS XP³ Light - Acetal Nickel http://frozencpu.com/products/23233/

This one will look better than copper in my build, and metals will be mixed anyway because the GPU block only comes in the Nickel version.

 

 

 

 

 

GPU block: EK-FC780 GTX WF3 - Acetal+Nickel http://frozencpu.com/products/23943/

Full cover. Not much to say about it. Only one for this PCB design.

 

 

 

 

 

Rad: Alphacool NexXxos UT60 Full Copper 420mm - White Edition http://frozencpu.com/products/22074/

I think 3x140 should be more than enough to cool CPU+GPU on low RPM

 

 

 

 

Rad wall mount: XSPC Radiator Mounting Bracket set http://frozencpu.com/products/10347/

I'll get some solid screws for them. These aren't meant for hanging radiators on walls, but they look solid enough to hold about 1kg/2.2lbs of weight each... And a full rad won't even be that heavy.

 

 

 

 

Fans: Noctua NF-A14 FLX (x3) http://frozencpu.com/products/18314/

Since budget isn't a problem, I decided to go for solid, quiet fans. I will spray paint the sides white at some point.

 

 

 

 

Tubing: PrimoChill PrimoFlex Advanced LRT http://frozencpu.com/products/17866/ or Masterkleer http://frozencpu.com/products/12979/

Not really sure what color/diameter, but that doesn't matter. Any advice on which brand I should go for?

 

 

 

 

Coolant: Gool ol' distilled water

I don't want to take any risks with dyes. Besides, they would ruin the look of my res.

 

 

 

 

Additives: Feser Base Corrosion Blocker http://frozencpu.com/products/21400/ + Mayhems Biocide Extreme http://frozencpu.com/products/17710/ or IandH Dead-Water http://frozencpu.com/products/11744/

Here's a very important question. First of all, does "PT Nuke", aka Copper Sulfate, cause problems when mixed with glycol based corrosion blockers?

Other question, which one of these biocides should I get? They both use CuSO, but Mayhems Biocide also contains citric acid. This makes the water acidic, and thus less friendly towards biological growth. Though will it cause problems in a distilled water + mixed metal loop?

 

 

 

 

Fittings: Compressions, nickel coated brass http://aquatuning.nl/product_info.php/language/en/info/p4199

I found few that for some reason are twice as cheap as all others in the store I'm using. Anything I should watch out for, or is it all the same?

 

 

 

I will also include things like fan controllers, thermometers, UV cathodes and some other minor stuff, but that doesn't really matter all that much.

 

 

 

 

So, what do you guys think about this loop? The last thing I want is spending €650 on something that will break the very next day.

Not really to do with the loop, but in terms of cathodes they are really bulky and have a habit of fading quickly. I'd recommend having a look at the rigid pcb led strips that mnpctech.com has recently got in. They're a bit more pricey but are far brighter/more effective than any other led or cathode alternative that I've seen and all the components are high quality.

If you'reinterested you can get them here: http://mnpctech.com/case-mods-gaming-pc-liquid-modding-custom-computer-mnpctech-overclock-cooling-fan-grills/uv-12-30cm-dimmable-pc-led-strip.html

 

When it comes to D5 pumps, go for a pwm controlled version (any rebrand will be fine) as you can setup a custom fan curve in UEFI or software to control it rather than a physical dial.

 

Also when you say "mount externally" for the res and rad do you mean outside the case? in which case I'd look at how you plan to do this. Some options are a waterbox/radbox, but at the very least you'll need to sort out the right mounting system and hardware.

Edit: Forgot to add that you'll need a UV reactive dye for the UV lights to have any effect, and I believe you can get some that are clear so it won't ruin the look of the loop without light exposure.

[Kogure_Chan]

I'll get UV reactive tubing so I don't have to pour any dye into the loop.

 

The res actually comes with two holders and screws, so all I have to do is drill holes in the wall. As for the radiator, I'll use the steel mounting brackets I talked about. They will be screwed to the radiator between the fans and the rad itself. The same screws I use for fans.It should work.

 

I'll also look into the PWM pumps and LED strips you mentioned.
