S&C UnderGround Looking for power rack

Looking for a power rack for a home gym. Basically do squats, bench, and pull-ups. Been looking at Rogue racks and they're nice. 
 

The issue I have is, brand new house, and I can't bolt anything to the garage floor because of tension rods in the concrete. 
 

So I need a stable rack that can't be bolted to the floor. Suggestions?

I have a Titan x2. It says to be bolted down but I don't and it's fine. If you put plate storage on there you are set. With weights and attachments mine is around 600lbs.

Matrix Mega Racks. Very heavy, all the functions. But rather expensive. Titans are a reasonable value. Maybe check out Sorinex
