ah,found out that they are 6mm pipes. also,the triple radiator has 10mm fittings. will the pump have enough pressure to push water through the whole system? the initial kit is found here:

and type in "terratec mystify"
well, it has a eheim pump,which can only be good.
looking at waterblocks, i can get an alphacool nexXxos, or a dangerden maze4, are these any good as waterblocks?
