I'm looking to put a Triple Radiator on the back of my Antec 300 case and go water cooling. One thing bugs me though, measuring where the Rad would fit back there with a ruler and accounting for the Radbox that would be there. Seems like the Radiator will come in contact with the rear PSU cable. Has anyone had this problem before with a PSU on the bottom? Are there power cables with a right angle in them?
