They are actually still mounted on the side panel , but right up to front of it this way when it turns 90 deg. it covers right across the front of the reef . I have a couple pics , but hard to tell from them .Pump is located on on side of the sump from there piping goes up to a tee , one line continues straight up to the seaswirl , and the other goes under the stand and back up on the other side, make sure you use valve on each ( which I'm sure you would ) but they are neede to adjust flow to equal the output evenly from each one.
Here's a few early setup pics of it
