We usually

Keep in mind that next year's electronics may almost weigh the same, but the weight distributions will be more concentrated due to a more compact design. What we "usually" do for mounting these systems will have to at least be reconsidered next year.

As for the above oak/lexan debate, here's some data. The other mentors and I have always asked ourselves what the real benefit of lexan over other materials was, so I just did some research.

According to matweb a typical lexan sheet has a density of ~0.041 lb/in^3 whereas most solid oak hardwoods have a density of ~0.021 lb/in^3. The flex testing of lexan was done with 1/4" sheets and yielded ~65% flex resistance over with-the-grain testing of oak, yet for almost twice the weight of oak. Hence, for the application of mounting electronics I think it's safe to say that typical 1/8" thick lexan and typical 1/4" thick oak are about equal when considering "will it work".
