I have a Thermaltake Armor LCS case, equipped with a fairly standard pump, reservoir, and 2 x 120mm fan radiator, as comes with the case. Currently I am using it to cool my moderately overclocked (2.4 --> 3.0 GHz) E6600. I am looking to buy two new graphics cards, probably 4870s, and watercool one (or both...), but I suspect that my radiator is not large enough - would it be able to handle one, or even two graphics cards being added to the loop? All help is appreciated, I am no expert on watercooling!
