Im in the process of doing a system upgrade. im upgrading gpu to an asus strix gtx 970 as soon as there in stock lol. At the same time i would like to change cases to something that i can do a custom loop in in the future for cpu and gpu once a good waterblock for the 970 is available. As for the rest of my components i am currently using an Asus sabertooth z77, core i5 3570k overclocked to 4.3, rosewill capstone 750w semi modular 80plus gold, and its housed in a zalman z9 plus. When i do this loop it will be the first custom loop i have ever done so i dont know how many rads i will need to keep everything running cool so on top of case suggestions if you could also suggest rads tubing and any other information i might need i would appreciate it.
