I have a friend with a 3D printer and he's making the ducts for me.

I got the S5 over the weekend and hooked it up in my laundry room.  It's loud, but it's not as loud as I expected from everything I read.  I used some tin foil to cover the bottom of the unit and then some more tin foil at the back to duct most of the hot air out my dryer vent.  The laundry room did get a few degrees warmer, but I think once I get the ducts on and get all the hot air to leave through the vent it will be better.  I'll try a couple different fans to see what it does for noise, but stock fan is something I can live with and the box runs around 50*C which is great.
