Have you ever built a PC cooling alternative from a window? This mod is an interesting cooling setup that is funneled out of the window. It could have better effect especially during winter times.
To collect the outside air, a dryer ductwork was attached from the window to the PC as it uses a dryer hood and a PC fan. To filter the incoming air, a scotch brite pad is used while the gravity is closed by a damper. The quick connect is found inside and the filter and hood on the outside of the board. During summer, the hot air from the PC can be exhausted to reduce thermal load.
