Okay, sorry for that little typo, didn't mean flow indicator to be the same as the method to trap air bubbles in the res, but as 2 different things. (ie if the flow meter and the method to trap air would still be working.)
Next to that, I don't understand why a res in the second compartment would be a problem? you just put 2 tubes through the cable management holes? On one of the preview/interview videos on teh youtubez, one of the corsair spokesmen already spoke about putting a pump in that compartment to hide it. Or do you mean that the res has to be in the highest point of the loop?
And to gts250: that specific res was the version without an included pump. There is a second variant with an EK-branded DDC pump for 30 euros more (don't know how much difference in dollars exactly), the EK-DCP 2.2
