Power consumption and living comfort are important factors for me. I  
figure 4 3.5" drives is not going to be a huge problem if done right,  
after all my Mac Pro runs 4 and it's pretty quite. One major thing  
that I found with 3.5" drives is they are a lot quieter if you use  
them in cradles floated on rubber bushes - you don't get that nasty  
Beats interference if you have more than 1 7200rpm drive :)

Power consumption is something I'd like to keep reasonable. Maybe  
under 200W at idle if at all possible?
