Personally with todays retail price madness I am not sure if Thermaltake are doing that bad a thing, more affordable cases for enthusiasts is no bad thing.
I would have loved a Caselabs case, but the price, lack of included dust filters, and complex ordering and importing process make it a pipe dream and a complete put off for many. All things that Caselabs could address and improve upon to entice potential customers.
One day I envisage morgages for computer cases and GPU's, most of which simply end up at such inflated prices because it's what the consumer thinks it's worth.
