About wide: I hope you make it 16.9" (16 15/16") wide to fit standard stackable hifi/home cinema equipment (and also wide round feet in crome would be cool). This will also add space inside making more room for air/cooling... making it less noisy (or so I hopeXecuter said:how you would do that with multiple hard drives and not making it super wide i have no idea
Else: incredible cool idea!
