GPU Upgrade

I have an origin genesis pc and would like to buy a gtx 970 ( gigabyte g1 ) card and I was wondering if it would fit in my pc?
any help would be appreciated

If its the genesis rig Im thinking of (reverse mounted like the raven cases) then you can fit the 970g1 plus the kitchen sink. An image or product link to your exact machine would be handy for clarification.
