Yes fill port up, with the fill port down it fit perfect. The fill port is now up facing the front of the case, facing back will require cutting. Not a big deal, fans are holding it fine until I get around to modding.
Here is what I did. I mounted it with the fillport facing up, and at the rear of the case with the tubes on the right. I did not slide it over to the right in the bay area of the 810, and iinstead have it slid over to the left/rear. First I mounted the fans (corsair sp 120's) to the bottom side of the rad. I then put a screw through the top of the case where the outer fans would normally go. I then placed 2 fans on the top of the rad without screwing them in. I then took the whole thing (rad, 2 bottom mounted fans, 2 nonmounted top fans), and lifted them up into the case. I then put the screw through a hole of the unmounted top fan tray, and lined it up with the rad. I did the same thing with another screw and got it so I could let go of everything. From that point I just lined up the rest of the holes and tightened them up. so the top screws are set in from the ouutside of the case and pull up/tighten the whole unit from the inside. I was able to do this using all 8 120mm case mounting holes and no mods. I was able to do while just barely clearing the cpu power cords. The only thing I had to do was go to home depot and buy 8 screws to match the long ones swiftech supplies. the only downfall I can see from is more space taken up inside the case with everything mounted inside, as opposed to have 2 fans and rad inside, and 2 fans mounted outside. If anybody would like a pic of what I am talking about let me know.
some things i'd like to see in future designs if swiftech is going to pursue this market:
1. design a pump with 2 barbs on one side, this will probably improve compatibility with more motherboards.
2. instead of gluing the plate on the top pump, allow it to be removed and re-mountable in 90 degree turns. I removed mine and found that you can only flip it 180. Also broke one of the little pins holding the top plate as I was prying on it to reorient it. I was able to put it back to the original position without any problems.

FYI, I could not fit the H220 at the bottom of my particular CaseLabs SM8 build. I have three 25mm thick FlexBay intakes and a bottom mounted AX1200i PSU. I'd have to remove the lowest FlexBay intake or relocate the PSU to make it work. I'm not doing that. So that leaves H220 mounting in a FlexBay 240 Radiator Mount or in the rad mounts up top.
