I like 'em a lot. Here's a Big Fogger on my latest "creation". A CNC Hammond 1590G with a DNA200 powered by a 1000mah LiPO pack. The only holes in the case are the buttons, display and the 510 connector.
The Fogger has the air channels drilled out to 3mm.
Hey, AMD, what size did you expand those wick channels to? That's my next modification to the Big Fogger and, probably, the 4.1s and 6s as well.
