Hey!
I recently just finished my TR4 570x RGB Build [sans 2x8gb sticks of ram (waiting for the prices to hopefully drop...)]
I have the Enermax TR4 360 front-mounted in my case. I had read online that getting an AIO to fit on the top in a 570x was pretty slim. Some folks were able, but stated that the fans would be pressing against the RAM or MoBo, and I wasn't too keen on that idea. Personally I think it looks great mounted to the front. There's a ton of empty space toward the front of the case, there being no SSD/HDD bins. Also having as much real-estate as I did I was able to take the 3x stock SP120s and put them on the back of the radiator to help pull air through.
As for the RGB set up:
4x LL120 RGB 120mm Dual Light Loop RGB LED PWM Fan
LL140 RGB 140mm Dual Light Loop RGB LED PWM Fans - 2 fan pack with Lighting Node PRO
I got the 4x LL120s for the front (3x) and 1 in the rear. The 2x LL140s are for the top. They all fit flawlessly, so it's something to consider instead of 6x LL120s, if you so fancy!
The 3-pack of LL120s is listed as $120. Each LL120 is $35, so $35x3 = $105. This means $15 for the LNP whereas the 2-pack LL140 is $100 which each fan being $40. So $40x2 = $80, meaning the extra LNP cost $20. After doing this math, I just realized I sabotaged myself $5 bucks, d'oh!! [All prices based on Corsair.com]
CORSAIR Commander PRO (Christmas gift actually)
CORSAIR Lighting Node PRO
CORSAIR RGB LED Lighting PRO Expansion Kit (This gives me a total of 8x RGB light strips. I have 4 on the back of my monitor and 4 on the outside edges of my case.)
Your parts list looks to be the most cost-effective.
Again, I took the 3x stock SP120s that came with the 570x and attached them to the back of my AIO radiator (360) with 3x LL120s on the front. I mainly did this because I didn't want to leave 3 perfectly good and fun fans unused. =]
As for the connections, I have all 6x LLs plugged into the Commander PRO and 1 of my RGB hubs. The 570x has 6-fan RGB Hub already attached, and one of the multi-fan packs will give you a 2nd 6-fan RGB Hub, which you might not need. Since I kept my 3x SP120s, I needed the 2nd RGB Hub. I used double-sided tape and just slapped the 2nd RGB Hub ontop of the 1st one in the case, works perfect. You'll find it's going to get REALLY tight in the back of your case for cable management with all these goodies. Basically the Commander PRO drives my fans, and the Lighting Node PRO drives my strips.
Actually... I can draft up a visual diagram of how I have it all connected later if you'd like.
If you put your AIO radiator on the front of your case, you won't have an issue fitting ram.
I hope this makes some sense! I feel I lost my way trying to properly describe everything. =]
