Help with building watercool loop?

I'm newbie in watercooling. I only have closed-loop kit (CM Seidon 120XL).

I'm thinking of swapping case and cooling. Can somebody assist me with watercooling options for Corsair Obsidian 750D? I think that EKWB HFX 360 -kit fits Obsidian 750D.

Cooling and casing related things that I'm going to buy:

  • My current PC looks like this. I'm not going to swap any other components than cooling and case, as I said later. http://i.imgur.com/ra1N69m.jpg

    My current components:
    CPU: AMD FX-8350 - 5.2 gHz
    Cooler: CM Seidon 120XL - Push & Pull

    MB: ASUS M5A99X EVO R2.0
    GPUs: Dual ASUS HD 7870 DCII - CrossFireX
    SSD: Kingston V300 - 240 GB
    HDD: WD Caviar Green - 2 TB
    RAM: Kingston HyperX Genesis - 8 GB
    PSU: SilverStone 600W
    Case: Fractal Define R4

  • Now, because I'm newbie, how should I build this loop? Can 360mm radiator handle both GPU's and CPU, or do I have to get another radiator? Also, if somebody could state flow directions and other things a bit, that'd be nice. Sorry about my english (and bit bad pic).


    UPDATE:


    Is using hard tubing good idea, and is it easy enough for newbie? Also, should I use green or red way from CPU block to radiator?

    as long as you have one continuouse flow, there will be no problem. Have the pump be below the reservoir, and a single 360 rad will be enough for all three components, but will be about the minimum cooling surface area you'd want. a good run would be from reservoir down to pump, up to second gpu, then up to first gpu, then up to cpu, then up to radiator, then back to reservoir. order of the parts in the loop does not matter whatsoever, what you want primarily is clean tubing runs so your system doesnt look like a zombies intestines hanging out. a nice addition to this loop would be a be an additional 120mm rad at the bottom. these are the only real suggestions i have for you to make a nice clean looking system (can also put a 120mm rad on the back)

    if you do care about order (only 2 degree difference between coldest point and warmest point of your loop anywys) after the two gpu, put a 120mm rad on the back of the case, then go directly from the first gpu to that, and then to cpu, then to secondary rad.

    Brantyn, please check my update. Also, do you recommend soft or hard tubing for this system? I know hard tubing looks awesome, but is it possible in this future build?

    I recommend hard tubing between the gpu, and down from the reservoir to the pump, but otherwise soft tubing gives you more options and is cheaper. (hard tubing requires more complex fittings)

    the red option you have listed implies another radiator, which would be better than no additional rad

    and doing a push out towards the top like an exhaust would be my recommendation for airflow (then try to have intake fans on bottom and back)
