I'm also planning on using a
Brick Wall Surge Suppressor along with an Uninterrupted Power Supply (conditions the power), in addition to the hum filter.
I should not have any humming goin on.
If I do have any after all this, I'll probably go with the Ebtech HE-8 Hum Eliminator 8-Channel Single Space Rack I saw at:

By God, that ought to do the trick for sure! If it doesn't, then I'll get a box of ear plugs for the crowd...
