I forget how much storage you said you have now split across however  
many drives, but how about replacing them all with a $175 1TB drive?
You can tell her you're helping the environment by not using so much  
electricity spinning all those drives all day and by not running yet  
another noisy/hot machine.

Don't forget about the network bandwidth you're saving by keeping all  
your myth data local. Everyone in my house noticed when I stopped  
throwing video all over the network.
