Want to water cool my CPU and GPU, need some help please?

I am wanting to cool my Intel i7 4770K haswell CPU and my GTX 780ti. I have a NZXT Phantom 630 so I have plenty of room for radiators, 1x 360 2x 240, I am unsure what radiators to use. I would like to know wich kind of reservoir I should use, drive bay or not, Pump and reservoir hybrid. As well as what water block I should use for 780ti, I already am planning on using the XSPC Raystorm for my CPU. I plan on using 3/8 x 1/2 tubing and compression fittings.

    1. I will recommend a 360mm radiator and a 240mm radiator, as that will cool more than what your components produce. For the radiator, use XSPC AX series radiators. They are somewhat slim but great performing.
    2. NEVER get a bay reservoir, as there are two issues: a. You cannot use rigid acrylic because when you pull out the reservoir to refill/fill, it will disconnect. b. For normal tubing, you need to leave a little slack to allow for you to pull out the reservoir, making you use more tubing and that can cause kinks that will stop the flow.
    3. NEVER get a pump/reservoir combo unless you need to, as the pumps are usually less powerful than the standard ones to save space.
    4. I recommend EK Waterblocks for the GPU water blocks, be sure to get the nickel ones for the best thermals.
    5. For the pump, use a Laing D5, they are the best performing pumps and are less prone to fail.
    6. I also recommend EK Waterblocks for the compression fittings.
  2. Thank you that was very helpful, one more question if that's alright for thermal past I've been told Arctic MX-4 is good for both CPU and GPU. Also there is no copper block for the 780ti, which is better Acetal or nickle or Acetal+nickle?

    For the thermal compound, gelid GC extreme is the best for the CPU, and Arctic MX-4 is the best for the GPU. So yes, I would recommend Arctic MX-4 for both. I will recommend the nickle or acetal-nickel, but I would personally go for the acetal+nickel for the looks.
