"Overall I couldn't be happier with what Montech have achieved with the Air 903. A budget friendly, excellent looking and great performing Mid-Tower case that's not going to break the bank, yet can support up to E-ATX motherboards with a generous amount of included fans to cool the hottest of hardware!
