I will be using this board in Stacker832 and thought about organizing airflow from cpu heatsink (ultra 120 extreme) towards the top exhaust, either towards the back of the case.

If somebody could measure or tell if that would be possible using HR-05 SLI/IFX (mounting it so that it blocks first pci-express slot)? Or is the slot itself is too tall and it cannot be positioned in that way?
