Can I still bleed out air bubbles on set-up?

[dogin]

Currently have an EK 150 reservoir with the fill tube on the reservoir top port and the rad out to res in on the bottom port of the reservoir. This tube arrangement with my PA120.3 in the top of my case limits the number of drive bays I can use. I could get back a couple more bays by moving the reservoir up under the rad outlet with a short tube and use the top reservoir inlet for the rad out. Could put a 90 degree fitting in one of the reservoir bottom side ports with a fill tube to the top of the case. Since I turn the case upside down and fill it as I connect tubing (reservoir fills first), I am not too concerned about filling it. But will it still bleed off air through the reservoir bottom side mounted fill tube (or will the air bubbles just be sucked through the loop?????).

Hi dogin
I would not recommend it basically you will be dragging air back into your loop. The way you have mentioned would cause problems. You can do it but its not the ideal setup.
Why dont you mount the res at the rear of your case ?

Thanks for the advice. Guess I will leave my configuration with the traditional reservoir mount (also looks like I could put another bottom screw on cap on the reservoir for more port options and run the reservoir horizontal with a top port up to a fill tube and one port down to the pump? I was trying to get more bay space as only like two hard drives in my 4in3 bay cage for cooling purposes. But, it looks like the new raptor 300GB drives may offer a solution to that problem. Have thought of external reservoir mount and may try that.
