Calling the Cougar Panzer Max a tank is something of an exaggeration but at 266x612x556mm (10.5x24x21.9") it is certainly large and capable of housing even eATX motherboards.  The size also allows up to eight drives to be installed as well as eight 120mm or almost as many 140mm fans or the equivalent radiators, with a full installation you will be glad of the handles on the top.  TechPowerUp gives this case high marks but the Panzer Max did fall short of perfection, see if you agree with what they felt could have been better implemented by Cougar in their full review

"The Cougar Panzer Max is a full-tower representation of the Panzer chassis. It is larger, bulkier, has more space, and looks a lot more menacing to boot. It really does resemble a tank, which is what "Panzer'' means in German. So in this review, we take the Panzer Max for a joy ride, fill it with some ammunition, and see if it is a straight shooter."
