Home Made Cold Smoker

I came up with this idea of a cold smoker. 

Basically the microwave at the bottom will hold the smoking tray from A-MAZE-N.  I am going to use simple aluminum ducting to go from the microwave up to the PC case.  The aluminum ducting would snake back and forth inside the computer case and then came back out and up to the mini fridge.  There will be a PVC vale vent that comes out of the microwave to control how much air flow comes into the system and hopefully will create movement of the smoke.  If I have problem with movement then I will put a small computer fan in some were, like maybe the chimney to create some movement.

The three fans on the pc case will each have their own switch and so its my thought that I can some what control the temperature in the fridge for cold smoking.

Also if I need to I can put a small pump, reservoir, and misting nozzles in to the computer case and hopefully create some added cooling capability.
