Cooler Master Cosmos Pure vs. Obsidian 800D

Well I run a music recording biz. The reason I need to change case is that my CoolerMaster 330 Elite case doesn't have soundproofing, vibrates even with my HDs in GrowUpJapan soundproof caddies. I also have a HD that goes in and out of the PC all the time. It's a nightmare to work on the PC. I have to remove everything to get at the motherboard. Changing hard disks is a 20 minute job.

I need a very quiet soundproof case that doesn't allow vibrations to get from HDs to the case, doesn't allow vibrations to get from the HD 5.25" soundproof caddies to the case, easy to work on, and is easy to add and remove HDs.

I meed hotswap HDs and soundproofing.

I have an i7 overclocked to 4Ghz with a Mugen II air cooler.

Damping airborne noise needs closed construction without direct noise escape paths anywhere towards you: If you can see insides through meshes and holes so can noise get out. This factor decides can case have any chances of containing noise and hence is very important. And door can also muffle noise from 5.25" devices.

Preventing vibration induced noises needs soft mounting (elastic suspension best) for HDDs and vibration resisting panels (like in Antec P-serie) or mass damping with bitumen (like in Fractal Design R2) or something similar dense/heavy stuff. This could be said to be related to do you want "drop parts in" solution or are you ready to do some work for realizing full potential of otherwise acoustically good design case.

In case of some 5.25" device or box is vibrating it's pretty much impossible to soft mount it so only help would be increasing amount of mass damping. If there's hard mechanical contact between HDD and outer 5.25" shell in those GUP caddies then design is simply acoustically bad. HDD vibration is far worser noise source than airborne noise of drive itself (ever tried running HDD on hand or on soft foam) which can be muffled by proper case so preventing that vibration from getting to case structures or anything which could vibrate along is primary goal.

Also hot swap backplanes are acoustically rather bad because they need precise positioning and rather hard fixing of drive for aligning connectors properly and for preventing stress to connectors. (Molex and PATA were strong but SATA connectors are flimsy)

Those light as air foams come as possible lasttouch only after these steps (along quiet components) and needs to be at least ~1cm thick.
