Built when Netflix first took away password sharing. Thanks for the heads up Netflix! Would not want to start this project now 😂
Edit: adding temp and specs

I am guessing the egg-shell foamed enclosure is for the sound, but you probably have a bunch of sound coming from the fan port, nessisary for ventilation. You can cut a lot of the sound but maintain the airflow by cutting an s-shaped ducting spanning the width of the enclosure. The shape will drop the sound, while then ducting keeps the air flowing. I would not recommend any sorts of filters to block the sound because they are a bit too restrictive for an enclosure in your style.
I get about the same affect by placing a layer of the foam on the wall behind the fans. But you’re totally right. Without that lil bit the fan noise from the intake and exhaust was a lil noticeable
Also high density mass loaded vinyl works better for your enclosure. Foam helps against reflections but they still let sound trough. Mass loaded vinyl basically adds mass to the walls of your enclosure which stops them from transferring the sound waves to the outside.
Does it help to point out this is vinyl backed foam 😉 really thin vinyl sheet on it, but it helps
