Hello, I am thinking about building my first water cooling rig. I am thinking about getting a XSPC EX240 rad, XSPC Raystorm cpu block and a Danger Den CPX - Pro pump. I don't know whether this is a good build or not. I am considering Monsoon Free center compression fittings, and haven't decided on tubing. I will be putting this system in a Antec P280 case ( just saying in case it makes a difference) with an i5 3570k. I am looking at a budget of around 250$. I will be getting my parts at Microcenter (the one in Tustin). I would like you have your inputs and thoughts about this setup. Also, I'm wondering if water filtered my the revere osmosis process is any good for using in a loop. Another question: If I use UV dye or Primochill tubing, then do I have to get a biocide?
