So I finished my first and second gaming rig builds and now I am looking to upgrade my personal system by going to all water cooling. I have an Antec h2o 620 right now and I'm looking at purchasing the xspc raystorm rx240 extreme. My case is the corsair 600t white. My first question is when I get the funds together for the water block (gtx 670) what kind of difficulty installation wise am I looking (I am a novice water cooler at best). The next question is because of limited space in regards rad mounting options, would the phobya xtreme 200mm rad be enough cooling for the gpu if i added it to the loop? I'm sorry in advance if any of these questions are too stupid, but hey if I don't ask them now I may end up asking dumber ones down the road. Thanks in advance for any help offered.
