i have had a set with those fittings, and they started to leak after a while, points you have to watch really good is: your tube has to be cut perfect straight, and still then there can be no force on the tube.. to be honest, i'd never use them again..
good luck! and hope it wont leak!
also: i have a chieftech mesh bigtower here, its old.. some stuff cut up, but the side panels fit your case (everything is same exept for front panel afaik).. if you have friends traveling between holland and poland, they can pick it up for free always helps to have spare side panel or something
