I received my Whisperflow hushbox from Dave Beatty this past Friday and thought I might post some pictures for the benefit of this forum.

The enclosure is about 17"x18"x9.5". The projector is mounted on top of three long screws that allows for very convenient tilt adjustment. Four screws are used on the front plate to open up the enclosure. It is necessary to use something to prop up the enclosure itself like the wooden blocks that I use. Dave provides a circular piece of Edmund Industrial optical glass to place over the gap in the front but does not install it beforehand since some may not want to use it. I found that covering the front area did not make much of a difference in noise if you sit behind the projector as I do. There is a T-shaped shelf within the enclosure and an opening in the back of the bottom plate to allow cables to pass through.
Overall, I found the build quality to be very good, and the noise of the projector has been reduced to about 1/3 to 1/2 of the noise level without a hushbox. Unfortunately, it is below the threshold of my SPL meter (50dB) so I can't do any measurements. Since I sit so close to the projector, it's still audible and perhaps there are some things I can do with the provided acoustic foam that might improve things further (any tips would be appreciated).
The enclosure uses a Sunon fan that is very quiet and uses a variable voltage AC adapter to control the speed. Even at the full 12 volts, the fan is barely audible. The right side of the enclosure does get warm to the touch during the viewing of a movie. I found that most of the noise escaping the enclosure is actually coming through the fan area. Because of the clear plexiglass, there were obviously no problems controlling the projector with my remote while inside.
Total price including shipping was $425.00. Wait time was about 3-4 weeks and Dave was pleasant to deal with. For those that got in on the Dell deal, an LT150+whisperflow is still below the price you'd pay today from most places to get an LT150. Overall, I'm very satisfied with the purchase.
