This is my acrylic window mod, viewed from inside. U can see the silicon I used to stick it onto the case panel. The fans on the window is covered by panty hose, which acts as a filter. Why panty hose ? Cheap, easy to install. The other 2 fans on top of the panel will be retired soon. I've yet to figure out what to do with those 2 holes, but I will cover them with acrylic, until I can find some ways to make use of it.

The black arrow is pointing to my fanbus, one of the very first mod I made. All the casing intake & blowhole fans are connected to this fanbus, plus the switches for the neon. The wires tied together by white masking tape above it are the wires to the baybus switches.

Here U can see the fanbus, attached to the bottom part of the casing's inner 3.5" drive cages. I stick it there using Velcro. All the wires are connected to the wires from the baybus switches using modded Molex connectors, so that I can easily take it off . This will make removing both units separately an easy task.

The bottom black arrow is pointing to my 92mm Panaflo intake fan, soon to be retired as well. It's covered by 3 layers of panty hoses.
