I've been "researching" for days now planning to build my new computer. I think I have the whole list of parts needed for the build, and I hope that some of you can comment on the parts I've chosen. I'm going to put everything in a midi-tower, and the emphasis is on low-noise (while still being able to cool, of course).

The most important input I could get from any of you is whether or not my plan will give enough water-flow, air-flow and heat dissipation without maxing speed of fan or pump. I'm also very interested in advice on which air-flow directions I should aim for.

Loop configuration:
Option #1: Res -> pump -> 120.2 rad -> 120.1 rad -> Temp sensor 1 -> CPU -> GPU -> Temp sensor 1 -> 200.1 rad -> Flow Sensor -> Res

As for the temp/flow-sensors: I want to be able to calculate system load (Watts) by using flow and Delta-Watertemp (I believe the Aquaero is capable of doing this). I also want to be able to calculate the Delta-T: TempWater(out) - TempAir(in). I am aware that the pump will dump a "small" amount of heat into the loop, and that my power estimate won't be that accurate. As the heat of the pump is relatively low compared to the rest of the system, I hope it won't matter. En alternate loop would be to keep all radiators in succession like this:

Option #2: Res -> pump -> Temp sensor 1 -> 200.1 rad -> Flow sensor -> 120.2 rad -> 120.1 rad -> Temp sensor 2 -> CPU -> GPU -> Res
If I do the loop this way, I'll get a small increase in total tube length, but I will be able to measure temp. differences over the radiator set more accurately.

Air flow configuration:
I'm thinking of configuring the top radiator as an exhaust, and the front radiator as intake. I'm a little unsure of the radiator on the back, though. I might configure this as an intake too, just trying to keep a small positive pressure in the case (dust).

It took me a while to get here, especially regarding choice of radiators (small space, low air-flow). The big questions: Can it be done, will it overheat, will it be low-noise? Overachiever or underachiever? Is the pump strong enough to overcome the total resistance? Should I go for 1/2"ID instead of 3/8ID" tubing? Any advice is greatfully received, even small corrections and smarter solutions. Thanks.
