For the same price as its AirX ARGB, Montech’s Air 900 ARGB addresses several of the former’s shortfalls while adding a few of its own. These are after all $70 cases (give or take a dollar), and any extra features can only be counted as bonuses at that price. With both cases providing a tempered glass side panels and an ARGB controller, anything and everything right down to the number of fans is tossed into the tug of war for value. We received this one as a loner from GameGo Computers in exchange for providing the link you just saw.
Though the cardboard of the Air 900’s box is a bit on the tough side, the somewhat fragile expanded foam ball forms are all that was needed keep this lightweight model from moving around inside it. Packaged back-side-down, opening the box from the top allowed the case to slide out face down.
The Air 900 features top fan mounts for the builder’s choice of two 120mm or 140mm units, with the slots aligned so that 120mm radiator have an extra 20mm horizontal distance from the motherboard (44mm total from the standoffs). For a case that only has 26mm of vertical clearance above the motherboard, horizontal offset becomes a key factor in top-panel radiator support.
Power, reset, and RGB mode selection buttons add to the front-panel port section of two USB 2.0, two USB 3.0, headphone and microphone jacks. The RGB controller provides 22 integrated pulsing/streaming/scrolling patterns in addition to motherboard ARGB input and “off” mode.
The bottom features an even longer magnetic dust filter, with case tabs at the sides to prevent it from being knocked off. Removing it reveals four screws that secure an internal drive cage in the builder’s choice of two positions, allowing more space for either long power supplies or thick front-panel radiator configurations. Builders who face both space constraints may opt to remove the drive cage entirely. The drive cage screws catch the magnetic edge of the dust filter as its being removed, requiring the owner to flex the filter away from the panel to slide the filter past these points.
The tempered glass side panel is secured with a combination of thumb screws atop grommet-covered standoffs. Removing the scratch-resistant plastic packaging reveals its moderate tint and shine as a stark contrast to the textured black fish of the steel panel on the opposite side. Also revealed in these shots are the front panel’s side vents, eight-slot back panel with break-away slot covers (ouch) and factory-installed 120mm non-LED exhaust fan.
