The thing that impressed me the most was the insane CPU fan. This thing has three case fans, one CPU fan, two video card fans, and the normal PSU fan. Mental.
Block up the holes next to the PCI slots to avoid shortcuts.
Personally, I'd lose that rear case fan, cut out the honeycomb and fit a wire grille, and use some cardboard or hard polystyrene sheeting to duct that CPU cooler fan out.
