I've researched and haven't found much saying this has been done before, so here goes...
My desktop computer produces too much heat. Its a Core i5 2500K with 4 HDDs, 2 GTX 465's in SLI, etc, running on a 850W power supply.
In winter its nice, practically heats the entire house....the problem is summer. With the room closed it'll heat the room to 80-85*F even with a/c on a decent amount. That's too hot and it seems I'm stuck with either a higher a/c bill, no privacy, or sweating in the heat.
That's where this idea comes in. As it is, I have my case setup so everything exhausts out the back. It seems like I could just create a type of....plenum, that attaches to the rear of the case (to collect the hot air), then attach dryer ducting or something similar to the plenum, and route that outside through a window? Times when something like this has been mentioned before, people have dismissed it because of case fans not being enough to flow air through the tube, heat/water/condensation could flow back through, etc. With this: http://www.boatersplus.com/attwood-turbo-3000-in-line-b... or 2-3 80mm case fans placed inline in the tube, I think it would flow plenty of air to pull air off the back of the case and flow plenty out the window to keep water/etc out.
I pretty much already know how to construct the tube/ducting, and the window mount, but I was wondering about building the "plenum"? I don't have any good ideas for doing that.
