AnandTech wrote up a review of the ThermalTake A6000B Aluminum Case :
Unfortunately, the investment in the A6000B is by no means a small one. At 130 USD, our Thermaltake Xaser II A6000B costs almost twice that of the generic tower we compared the system to. Since a case typically remains constant throughout a computer's life, it is often the last item to be upgraded and the price of the A6000B will hold a number of users back. Truthfully, no case is going to offer a drastic performance or cooling increases but the A6000B seems to do a reasonable job compared to the generic competition. If you have cash to spend and are looking for a cool running case with good looks, do not rule the Thermaltake Xaser II A6000B out; even if it does not come with a power supply.
