Water cooling help for a newb

[Tampwns]

Hi, first time poster here.
Ive built a few computers before but now I am thinking about taking the step to water cooling for my new personal PC I've begun building. Im kind of daunted by the though so any advice on these questions will be helpful.
I have currently a HAF X Nvidia edition case and was planning on beginning with a simple processor only loop (i7 2600k which I would like to overclock), though once i get it figured out and also purchase a 2nd GTX 570, which I currently have one of I would like to eventually end up adding my GPU's to the loop. I just wanna start of slow though and get a good feel for water cooling first.
I was considering getting a XSPC RASA 750 RX360 or RS360. Ive read though that there may problems fitting this in my HAF X in a push pull configuration, is this so? Id prefer to have it on the inside of my case. Also are these decent choices as far as starting out water cooling is concerned? What is the major differences between the two RX setups and should I been looking at something different?
I dont mind upgrading in the future and or adding to or changing the system if needed. Would this be enough though in the future to add a GPU or SLI cooling mix into the processor loop with the stock pump and res?
Ive also read the tubing has a tendency to go cloudy with XSPC's stock tubing. Should I be purchasing a different brand of tubing with the kit if I end up going for it and what ID and OD tubing would be the best fit for these kits? Or has the tubing changed over time and this is no longer an issue? Would there be anything else I need to purchase with this kit to make things more ideal?
I know this may not be the place for this last question but it is semi related; I have not yet purchased a power supply and was wondering If an 850w power supply would be enough with some head room to run the pump, 2 gpus, i7 2600k, couple of HD's, and some other components. I dont know if it matters with the setup but my motherboard is an ASUS Maximus IV Extreme.
Im sorry for such a wall of text and so many random questions, but I've been putting alot of thought into this and every time I seem to decide on something or do some research I seem to hit another potential problem. My latest problem being fitting the kit in a HAF X.
Thankyou for taking the time to read this if you have and any replies is greatly appreciated, Im all ready to order once I finally settle on my best water cooling option.

OK, I can answer a couple things here as I'm in the same situation as you, (I have a HAF-X and want to move to watercooling).

The difference between the RX and RS kits as per the FrozenCPU website, "The only difference between the RS and RX kits is the thickness and performance of the radiator included. The RX has a larger heat dissipation rating."

This video shows installation and how it fits into a HAF-X, (seems to fit just fine on the inside).

Lastly, deducing from the video, the tubing seems to be weak as per the videographers of the video, recommending that you replacing the tubing with aftermarket tubing because of the kinking of the tubing that comes with the kit.

Well let me start by saying welcome to the forums. Ok so im not sure about the fit inside of your case with that radiator, I dont have either. You dont really need to run push pull config unless your using really restrictive radiators or need the absolute max airflow. However, the 360 is plenty for the cpu. It might handle one of the 570s with ok temps @ the cpu but its going to be marginal. With 2 you will probably want to add some radiator. If you have not done so yet I highly recommend that you look through the stickies at the top of the water cooling forum. There is alot of great information there that will help to explain not just what you need to do but why we do it that way. Your PSU should have plenty of capacity to run a pair of 570s a 2600k and your WC gear no problems.

The XSPC stuff is not bad, its not great either. I recently built my wife a setup with 2 RS 240s and the dualbay res/pump combo in it. We are both very happy with the results so far. The tube included with the kit is sufficient BUT you might want to look at some of primochill's UV reactive colored tube. Its much easier than dyes and it looks just as awesome. The other plus side is that its got a harder plastic mixed into it to help prevent kinking.

don't buy a kit...best advice I can give you. With that RX/RS kit, you end up with a crappy pump, a middle of the line block, mediocre tubing, and a pretty solid rad (assuming you go RX, the RS is rather old and as such, not so good). When you go to add something to your loop to upgrade, instead of just having to purchase a new block and drop it in, you now need a new block and a new pump...oh, and the pump is in the res, so you need a new res too. That first upgrade you're looking at spending MORE than the cost of the kit to make the pieces of the kit adequate...

Also, read the sticky, it covers a lot of good info that you should definitely understand before you even think about pushing the buy button
