I would include cooling fan, and a chunk of aluminum plate to mount the bridges on and possibly the Transformer, keep in mind all of these items, including the caps are de-rated once a certain temp. is reached. Also, if you use the typical centre-bolt & large disc mounting assy for the toroid, make sure no grounded object come in contact with the top disc or screw or you will have a shorted turn set up. (you will start to wonder why the txfr is heating up with no apparent load).
