I find the plastic top looks great. It does need two 3/8" to 1/2 inch holes over the hot spots on the center board.
It seems to me, if the Wizard or Sorcer works better with the top off, it would work even better mounted on the wall, top facing the equipment, bottom parallel to the wall.
Lastly, is there any consensus on power cord type ? I am hoping to use a relatively small gauge cord, with the new QSA treated wall plug and IEC plug.
