1. Does it actually help in reducing noise?
2. Can I do something similar with my case? Would it help me? I have 2 front (Corsair) + 1 bottom (Noctua) intake fans, then 2 top (Noctua) + 1 back/rear (Noctua) blow out fans. I think side doors are the only ones that I can insulate and I am not sure if it would help enough to be worth the hassle...
3. What supplies, materials do I need and where can I get them?
4. How do I do it?
Silent cases are not silent, not when it comes to performance (unless you have an overkill cooler or very big case for efficient parts), and noise dampening materials do not make it quieter, they just reduce the high pitch noise. You want quiet or silent. Start by reducing or eliminating noise sources.
Since I'm on a very similar path and at about 70% success (work in progress), ill give you some tips.
You want to get a very good airflow case. If it's tiny, make sure it has a breathbale PSU shroud and make sure you have it clean (tuck everything behind the motherboard). Recomendations: corsair air 540, Meshify C/s2, phanteks p600s, cm h500 among many others.
HDD and stock GPUs (even third party ones) are a pain in the ass. So you need to eliminate the HDD and mod the heatsink of the GPU with 120mm fans or buy a cooler like accelero or morpheus. For the CPU, get a massive air cooler like the ones that Thermalright sells, and make sure to run its fan and the case fans at 600-800rpm.
If you have an Intel highly oced CPU, delid and use LM or top paste if you are not comfortable with LM
Also. In the question 2, you give some details about fans, so i get that you think they are the most important. The most impactful thing is the case design. Fan placement mathers a lot but if the case is garbage, doesn't matter where you place the fans.
