I'd like some expert advice about which kit would provide the best value before placing the order. I want to cool an i5 clocked to 4.6 in a Corsair 650D case. I know OcUK do a pre-built water cooled 650D case, but I'd like to have the satisfaction of building the loop myself 
EK H3O Watercooling Kit - Supreme LT 240
EK H3O Watercooling Kit - Supreme HF 240

EK H3O Watercooling Kit - Supreme LT 240
EK H3O Watercooling Kit - Supreme HF 240

looks like I'd better order the other type from somewhere
