NZXT makes well build, well designed cases, as does Corsair. From what I read of AZZA-csaz, while their cases are Japanese SECC steel, and seem very well built, some of their characteristics are a little sloppy. No filters on 2x230mm side fan intakes.. that's a huge, HUGE dust magnet. no sensor wires on any case fans, made by Globe, and a 3-speed fan controller for a top 230mm exhaust... on the rear of the case? Looks wise.. not to bad, there are worse looking designs, in my opinion, but for some odd reason... the words Power Rangers come to mind, especially looking at the XT1.
If you are shopping for a case, make a list. Start with what you need... optical bay or not, mobo size, hdd bays or not, massive airflow-average airflow etc etc...
