To access the interior, simply remove the thumb screws holding the high-quality glass panel in place, or loosen the attached thumb screws on the side panel. The interior of the Phanteks G360A is actually quite simple. The dimensions of the shroud are such that it also acts as an external wall to the bottom of the chassis. It is made out of metal and feels extremely sturdy. Previous variants of this case had a small cutout in the center for PCIe power cables to be run through the shroud, which is no longer present on the G360A.
Turning the chassis around, the backside offers everything you would expect: a large opening for access to the CPU cooler's bracket and trench to offer sufficient cable-routing space. Due to that trench in the front of the chassis, you have 36 mm to work with instead of the approximately 15 mm across the rear of the motherboard tray. However, you won't find large grommet-covered openings. Instead, Phanteks placed plain cutouts on the side of the trench to ensure you can still route everything nicely.
There are three SSD mounts on the motherboard tray, but Phanteks only supplies two trays. If you want to fill that third slot, you will have to buy the tray separately. Another nice touch are the Velcro strips we have come to expect from Phanteks.
In the front underneath the shroud, an HDD cage holds two black plastic hard-drive trays. Each of these may be used for either a 3.5" or 2.5" drive. You may move the tray forward for longer PSUs, but as we are using the compact Phanteks Amp 1000, we won't have to. Above that is the aforementioned trio of intake fans. Their wiring is inefficient, so we will spend a little time making sure all of them are routed out of sight.
In the rear, the PSU bay is quite basic, with foam tips on the floor as a simple anti-vibration measure. Above that are the seven reusable covers for the motherboard expansion slots. Each of these is held in place by thumbscrews. In the very top is that aforementioned vent for an optional 120 mm fan.
The ceiling of the Phanteks Eclipse G360 comes with offset mounting holes for the radiator. Considering the pretty skinny case dimensions, it will be interesting to see how the 360 radiator will fit alongside a modern, high-end motherboard.
All the cables within the Phanteks Eclipse G360A are of the standard variety. There is only a single lead for the power switch as the enclosure foregoes the reset button and activity LEDs in the top. All the D-RGB elements are pre-connected out of the box, and you may connect generic ARGB lighting to the built-in controller as there is an appropriate cable. On top of that, the unit allows for motherboard control instead.
