Actually, the case I'm getting will take care of that just fine, should i eventually go that direction. There's a 5 drive bay cage at the bottom directly behind 2 80mm fans. So at the moment, I'll have 2 drives, each a bay apart, and if I had 3 drives, they would still be a bay apart from each other. Cooling shouldn't be too bad.

I really just am not sure about those other aspects of the array. Cooling was certainly a concern, but I thought that might be enough. Do you think it will be?
