Guess it's about time i share the impressive beauty of my rig now, since i'm sure everybody cares
The first 2 pictures show the elegant way i solved the way the casing doesn't quite close anymore, the 3rd the reason why it doesn't quite close.
The hose is connected to a bathroom evacuation fan which i placed in the kitchen. It forces the air through the hose and displaces the hot air in the case. I tried to put the fan in it's normal suction direction but that caused a enormous whooshing sound which you get when you swirl a hose around.
The 4th/5th is the instrument panel which consists of a cantilever micro switch to wake/sleep the computer, a potentiometer to regulate varistor which controls bathroom fans speed and a switch to power down a mechanical relais which cuts all power.
As you can see this compact design lets me sleep/wake the rig with a simple flick of a finger, regulate airflow in the case so the CPU temperature stays lower then 50° C on full load and an emergency cutout switch ( had a smoking motherboard once to many)
I offer this marvelous piece of engineering free to the community to copy.
