Side view of my 65. The ugly black tubing is a cable guard from Ikea that has all the wiring that runs from the T5 lamps inside to the Workhorse ballast mounted on the back of the canopy. The plate with the fan has 4 wingnuts that can be removed in order to slide out the lighting rack (hence the long black tube). The fuge sits atop the canopy which has a 1" lip around it in case some disaster befalls the surge and it overflows.. Water will collect in the canopy and dribble back into the display. From experience, this doesn't work *that* well but does prevent a serious flood.
