I'm from the "you get what you pay for" camp, at least in most situations. I've certainly obtained expensive things for great deals like we all have.
The nice thing about that case is that it isn't of rigid FORM, it IS of rigid construction. Its a modular case, it hides cables, it promotes airflow. You may even have to clean it more often, but most of us could use the extra encouragement to actually break down our towers and clean them. Maybe even reapply some thermal paste to a few surfaces. Heck, take a look at the wiring routing andor component configuration and try something new to improve cooling.
I think this case would do that for most people. I'd certainly enjoy owning. The only reason I have yet to shell out $200 for it yet is because I have other things to pay for first. Don't forget kids, it's just money
