The internal one has a fan. Do you think it would be ok to just disconnect it? Rest of the case has decent airflow so I dont see it being a problem.
Also, how does hot swapping a hard drive work on ICH9 (AHCI) and Windows? On nForce boards the drives would show up as removable devices that you could stop and then remove, they dont do the same on ICH9. My plan is to have 2 or 3 hard drives that i can backup data on and just hot swap them when needed, dont want to have to turn off the pc each time.
