I don't think the case is worth $140. I think it's worth $120 due to the high grade materials and finish. It was picked for cooling path, price, and quality, where no other similarly-priced cases could match it in one of those areas.
I hate paying $40 extra to get a second front fan. The other option would have been a single 180mm fan, but all the options there were either trashy or expensive
Antec Three Hundred Illusion would have also done the job nicely for less than half the price.
