If you look around on the forum, just for example in philipmania topic you will find photos of perfectly working rigs with 4 GPU directly in the motherboard. You can undervolt and maybe under clock a little bit if you have temperare issue, but it isn't anything impossibile to deal with.
That being said, using risers is more convenient and allows you to scale to more cards.
To conclude, crossfire is useless during mining, it's better to just mine with multiple independent cards attached to the mobo
