I just finished installing the Swiftech kit in my system, and I think that closed and open system each have their good and bad points. The good thing about the open system is that your water has to flow through the reservoir and so your system automatically rids itself of bubbles. It's also really easy to fill the system, especially if you have the reservoir placed higher than everything else. The fill-bleed valve system that came with the Swiftech kit enables me to fill the system and get rid of air bubbles, but I have to stop the computer and pull the fill-bleed valves out from their hiding place in order to use it. It's also a bit clumbsy using all those valves. The good thing is once the system is free of bubbles, the pump becomes almost silent (it scares me at times), and there is no splashing. One thing I did notice, though was that the total volume of water in my system is surprisingly small. I'm sure I would get better cooling with a reservoir because there would be more water in the entire system to soak up the heat. I think it's a toss up, but whatever you do, make sure you install the reservoir or fill valves above everything else in the system. That way the tubes will get rid of bubbles on its own.
