Also wondered about the Sonex foam they use haven't heard much about it, except that it doesn't last too long before breaking down. If that's the case I wonder why they don't use other material that will
last longer in the Tsunami Ultra Quiet mod
You may have read Ralf Hutter's post about sonexhere
I caught that post while seriously considering the sonex product for my customer's cases. Being that sonex is manufacturered in my own state, I presented this issue to Joerg Hutmacher, illbruck's Business Unit Manager here in Mpls, MN.
The willtec melamine foam SONEXmini is a great product for your application. Compared to conventional polyurethane foams, melamine has an unlimited lifespan.It does not deteriorate under the influence of heat, UV light or any other environmental influences. You can basically submerge this material in water for 10 years or more, take it out, dry it and it is as good as new.
Polyurethane has a fairly short lifecycle. In your application probably not much more than 5 or 10 years. Heat and other environmental factors break this foam down fairly quickly. Also, keep in mind that polyurethane is flamable and can ignite if one of your units overheat.
I hope that answers your questions.

For me, installing the fire retardent willtec foam instead of polyurethane was added bonus. I'm lucky to have such a great product made in my own back yard! I've installed sonex willtec in several modified cases for nearly a year w/o any customer complaints. You can find several of these customers in ars-technica's

will be posting a review of my modified Tsunami
VA3000 w/ willtec foam very shortly.
