Does anyone here have experience with something similar to what I am thinking? Any advice you care to share. Potential problems. Any input can be helpful and would be greatly appreciated.
First, think about static air pressure and the condensation of the air. Second, go for the cheapest material for you, for example if you can get 6 sheets of MDF 1/4" x 20" x 20" (using the acoustic panels), you can get a better sound proofing than using plexiglass. Finally, think in how the heat flow out of your box, so always try to set you airflow as more vertically as you can.
