I feel your pain, sir. From a guy who is building his first WC project, let me save you some grief. If you want significant cooling results (aka better than air), you are going to have to put your own system together.
Read everything you can on watercooling while saving your cheese. By the time you have your cash together, you will have a very solid understanding of what you expect to accomplish and which components will get you there. Even then, you still may make mistakes. Heck, just look as my choice of fans with the rad I purchased. Bad move !
It's not the fun way to do it, but it's better than buying a system, obtaining disappointing results, selling it a signficant loss, then building your own anyway, or worse, telling everyone you know that watercooling stinks, using your recent experience and results as an example.
Again, I am new to this; however, I do feel comfortable offering this advice after reading too many posts from people expecting sub zero temps out of plug and play watercooling set ups.
And yes, I'm being dramatic.
Good luck !
