Also, for aesthetics, you may want to have the maximum flow possible for your overflow. That way you can significantly reduce, or even eliminate the need for powerheads in the tank.
The tank I described above has no powerheads. I was not sure how that would work out but the reef, including sps(s) appear to be doing well.
You can sperate water and salt creep with a simple weather proof enclosure.
If you have low ceilings it probably wouldn't be bad at all, but I have 12-15 foot vaulted ceilings and a peice of conduit would look pretty hokey...
