ASRock Z97 extreme4 and Raijintek Juno X

all 4 ram slot is filled
If the RAMs have the tall/big heatsink, I think you will have problem. If the RAMs are the low profile or even have the low heatsink, you are fine.

I added the review/pictures for you, after you read them you know what I talked about.
