Eclipse G500A chassis out of the box

The updated Eclipse G500A chassis features a refreshed exterior design and optimized internal space. Despite its unchanged size, the cooling capabilities have been improved with the addition of new M25-140 fans. It is available in two colors: all black and all white. There’s also a version without pre-installed fans, which allows users to select their own fans.

The Eclipse G500A features an Ultra-Fine Performance Mesh front panel, which has been updated with a U-shaped embossing like the Eclipse G360A. The mesh panel doubles as a dust filter and provides various lighting effects with its metal-punched holes. The front panel also includes a new ARGB light bar, adding a luminous touch when lit.

The Eclipse G500A comes equipped with a side-opening glass panel, which is secured with a magnetic design near the front panel. Rubber strips are placed around the inner edge of the glass to cushion it during opening and closing and also help prevent dust from entering the casing through the gap between the glass panel and the chassis.

The Eclipse G500A comes with three pre-installed M25-140 fans. These 140mm fans provide ample airflow to help dissipate heat. If a different fan is desired or if the fanless version of the Eclipse G500A is preferred, the front fan can be replaced thanks to its modular bracket design with symmetrical brackets for ease of installation. The internal space allocation has also been adjusted, allowing for the installation of three 120/140mm fans at the top, though the largest water cooling radiator that can be installed at the front is 420mm, and 360/280/240mm radiators can be installed at the top.

The Eclipse G500A follows in Phanteks’ fine tradition with its storage device installation options. The accessory package includes two adapter brackets that allow for the installation of either 2.5-inch or 3.5-inch drives. These brackets can be mounted to the wall of the main compartment and support up to six brackets in pairs. The lower compartment can accommodate up to four brackets in two pairs, or two brackets can be combined into one group and installed in the center for a well-balanced storage installation, power supply space, and front water cooling setup.

The motherboard is installed with 4 cable management baffles beside it.

After the cable management baffle is removed, at most 6 storage device brackets can be wall-mounted.
In the lower compartment, up to four storage device brackets can be installed. An additional bracket can be stacked on top of two installed brackets, or two brackets can be stacked and installed in the center.

Along with the 2.5-inch dedicated installation spots, the Eclipse G500A also features three quick-release brackets at the rear of the case. The two cable management dividers on the left and bottom sides provide additional three 2.5-inch installation positions. Rubber plugs are also provided to cover the installation lock holes, giving a clean appearance even if you don’t have a 2.5-inch device installed.

There are three 2.5-inch quick-release hard disk racks in the middle of the rear of the case, and the left and lower side cable management panels also support three 2.5-inch device installations.

The main compartment of the Eclipse G500A has been re-designed to create a larger visual sense of space while maintaining support for hardware installation. It supports E-ATX motherboards with a maximum width of 280mm, making it compatible with most flagship models from major manufacturers. The top of the motherboard provides ample space, about 7cm high, for installing water-cooling radiators. Cable management is made easier with the added flexibility for the growing number of fans and ARGB connectors on the motherboard.

The Eclipse G500A has ample space for graphics card installation, with a width of 435 mm capable of accommodating various RTX 40 series giant graphics cards. There are also 3 slots for upright installation, but it is recommended to install a 2.5-slot graphics card instead of a thick graphics card as it can affect heat dissipation. The Eclipse G500A also supports general upright graphics card kit installation if the player does not have additional expansion card installations.

The PCIe slots are given a 7+3 configuration.

The rear side of Eclipse G500A has multiple cable grommets, which helps to keep the cables organized and hidden, providing a clean and professional-looking build. The pre-cable design and the cable grommets make it easier for players to manage the cables, ensuring optimal airflow and preventing tangled or messy cables. The rear also has a pre-installed 140mm fan and 7 expansion slots, allowing for multiple GPU and other add-on card installations.
