Yeah. that's my thought. I'm at a couple racks now, but I want a solution that will scale beyond that. Thing is, to be honest, the coraid crap will probably be more reliable (and cheaper if you include my time) than stuff I build myself for the first few units, until I learn what I'm doing, but long-term, I could be significantly better off if my idea works as planned, as my units are potentially much cheaper and have a whole lot more cache (and cache redundancy) than the coraid.

On the other hand, if I handle the 'beta' poorly, like taking it out of beta early, there won't be a long term to worry about.
