Mr grow pro soil PC case

Anybody used one of these? I want to grow 2 auroa indica in 6 inch pots. Would that be enough space for them? I'm a little concerned with his poroducts because he's so open about what it is used for it wouldn't be hard for feds to get info. Also just out of curiosity he said it costs 7/week to run. How the hell does a pc case cost 7/week to run? I've never heard of a pc case costing 30/month to run!
