one cpu and one video card? that is pretty strait forward and should only require one loop, pump, and radiator. decide if you want to go full-face waterblock on that video card or a GPU only waterblock.
then figure out what radiator you could fit in that case (sorry, im not familiar with it). you probably need a 3x120mm radiator with some decently flowing fans, or one 4x120mm rad if you can fit it somewhere (or two 2x120mm radiators if you cant). you seem to know what components you need, so just go online and shop around for them.
