Can the radiators be turned on their side so that the pump outlet is facing downward?

Also, are those G1/4 or 3/8 holes for filling the reservoirs?

This looks like a great product, gabe. Swiftech have never let me down before. In fact, I think that most people get into water cooling via one of the swiftech kits. I still remember mine was with the original Apogee GT as well as a D5 and MCRes + MCR220. Great stuff.
