I will work on pics. It's a retrofit, so no fancy shell or casing, just a single puck mounted to a heat sink with a fan and then I have the Storm X controller. I had it mounted inside the hood of my JBJ nanocube 24, but that tank is done. I mounted the Storm controller on the outside of the hood.
Heatsink/fan/puck is roughly 4.5" x 2" x 1/2" (not sure about the thickness as it's still mounted inside the hood. Less than 1" for sure.
Storm controller is 2" x 4" x 1" plus the knob...
