<font color='#000000'>Ahhh I am sorry man, I thought it was merely going to be a file server feeding your home theatre.
If you are going to use it for more than that, than certainly you will need more then standard cooling to accomplish what you desire.
Do you think you would see less noise and heat if kept in the noise chamber, or if you didn't keep them in there and didn't have to cool them.
I have 2 X 36.7 gig WD raptors which run at 10000 RPM are surprisingly cooler than my Maxtor 7200 RPM 30 gig storage drive.
Anyways, I really like the idea of designing your own rackmount case... i bet it would look so sharp.. just a nice gloss black rackmounted box....
I really hope you crawl in under the 30 dB mark man, but I dunno!
Good luck,
