Thanks folks! For anyone interested, here's a photo gallery with a ton of pictures and random videos of the build:

The nozzle on the end of the fog machine is really tiny, so I thought I could use beverage hose to pipe the fog anywhere I wanted. I originally had plans of it shooting out different tiny ports around the machine. Turns out tiny hoses don't work too well. I went to larger PVC pipes and they worked better as you can see in this video:

I then re-worked the piping again, even going so far as to add a 3D printed inline booster fan. That, along with drilling some strategic air inlet holes in the pipe got me the nice blast of fog you see in the final product.
The fog still wasn't over. Fog machines get hot. That I knew, but since this machine is going to run for long periods of time I was worried that one day someone would forget to fill it with fog fluid and the heater element would run dry and overheat. The electronics were configured to power off the fog machine after periods of non use so that it can't be left on overnight.
I'm definitely not saying don't do it, but if you do, don't underestimate how long it will take you like I did!
