The case
Sounds like a neat system, I would want almost exactly the same.
I assume you are planning to build it yourself and you didn't mention buying a box for all the goodies. You probably already know this but you have to have the right tower to accommodate the all the components.
I used to think that any old case would do if it had all the bays you needed but I am told that the case must be as up to date as the components or they might not fit or function properly.
