A Closer Look - Inside

To access the interior, simply remove the thumb screws holding each panel in place. The most noticeable element is the white cable-routing cover you have to remove if you want to install an E-ATX board. Montech placed a metal shroud inside the Sky One ARGB that covers the PSU and 3.5" HDD cage. While most brands merely offer the possibility of taking a 2.5" tray from behind the motherboard and placing it on top of the shroud, the Sky One actually ships with one here out of the box. If you look closely, there are mounting holes for another one. However, going for a vertical GPU mount will make these placement possibilities unusable.


On the opposite side, you will notice the cutouts above the motherboard tray for easy cable routing above the board's edge. Montech has included an ARGB controller PCB that features generic connectors, so you are not tied into a specific eco-system. It is powered by a SATA connector and sports cables to attach directly to the motherboard. Alternatively, you may use the reset button as an LED toggle switch. There are two more individual 2.5" trays here, which brings the total of these up to a solid three.


The main cable channel, which is hidden from view by the white cover inside, comes with several Velcro ties, so you should easily be able to route your cables and switch things up along the way.


Underneath the shroud, in the front, is a 3.5" cage with a plastic tray for the main drive. That said, you have to pull it out to add another unit on top of the cage. We have seen a steady decline in the need for such drives, so this is the bare minimum you will find in ATX enclosures these days. Alternatively, you may mount a 3.5" drive inside the cage and another 2.5" on top of it. All said and done, this brings the total storage count within the Sky One up to a very good five drives. The area above is solely used for air or liquid cooling, with the pre-installed fan at mid-height. The white cover is shaped to allow for GPUs to easily pass it while offering as much cable-routing room as possible above, for larger plugs like the 24-pin ATX one. If you look closely, you will also see the pre-installed GPU support bracket.


Looking at the bottom of the rear, the PSU bay is standard-fare, with solid, thick foam strips on which the power supply will rest. You will have to slide the unit in through the side of the chassis, which could be a tight fit as the PSU needs to squeeze past any cables routed to the bottom edge of the motherboard. Above that are the seven horizontal and two vertical expansion slots. Each of these is protected by an individual, reusable cover that is in turn held in place by classic screws. In the very top is the 120 mm ARGB fan. It is of retail-grade quality, with LEDs embedded inside the center hub.


Taking a quick peek at the ceiling, you can see the distance and space above the motherboard, so most air and liquid cooling setups should fit just fine.


All the cables within the Montech Sky One ARGB are of the usual kind—sleeved black and clearly labeled. As with many cases that ship with an ARGB PCB, the reset cable is usually used to control the lighting within the chassis.
