The Phanteks Eclipse G300A boasts an impressive feature set for its compact size. You can easily build your dream gaming PC within the G300A, due to its spacious main chamber. Harness modern powerful hardware, thanks to extensive support for ATX motherboards, multiple storage drives, and even large GPUs, such as the ASUS RTX 4090 STRIX. What’s more, maintaining this powerful hardware at optimum thermal performance is simple, due to the G300A featuring outstanding cooling efficiency. There is room for multiple 120mm fans to be installed at the front, top, and rear of the case, alongside mounting points for radiators at the top and front. Additionally, your fans will have ample access to air, thanks to the high airflow mesh that Phanteks have utilised in many of the panels of the G300A.

Phanteks Eclipse G300A Mid-Tower PC case at a Glance:

  • High-airflow design mid-tower PC case
  • Supports ATX, Micro-ATX, and Mini-ITX motherboards
  • GPU clearance of 390mm
  • Fully featured front I/O
  • Two mounting positions for either a 240mm or 360mm radiator
  • Three pre-installed D-RGB 120mm fans

Compact Yet Fully Featured

The Phanteks Eclipse G300A has solved the issue of modern hardware getting larger, by utilising its available space in clever ways. The main innovation is that the front mounting points for fans and radiators have been moved. The G300A features a dedicated bracket inside the front mesh panel, which allows you to mount your cooling hardware without interfering with your GPU. This simple update gives the Eclipse G300A an impressive GPU clearance of 390mm, or 360mm with both fans and radiator, more than sufficient for even the largest top-of-the-line graphics cards.

The top of the case also offers outstanding clearance for radiators, letting you keep your gaming hardware cool. With a 240mm radiator installed, there is 42mm of clearance for RAM, letting you use your favourite ATX motherboard. This emphasis on space continues into the PSU chamber, which boasts room for a 220mm power supply even with the HDD cage installed.

Cooling First

The Phanteks Eclipse G300A boasts an exceptional airflow design, that can maintain modern hardware at optimum temperatures, thus allowing for peak performance under heavy loads. There is ample access to fresh air, as the G300A features large high airflow mesh panels at the front and on top of the case. What’s more, there are multiple locations for 120mm fans. Three can be mounted in the front bracket hidden by the front panels, a further two can be installed at the top of the case, and a final one can be located at the rear, for a total of six 120mm fans.

Even more impressive is the choice of radiator mounting points. Like many other cases, you can install a 240mm radiator. In addition to this top mount, you also have the option to install a 360mm radiator at the front of the case alongside your fans, which won’t interfere with any other internal components.

Easy RGB

The Phanteks Eclipse G300A comes equipped with three fantastic 120mm D-RGB fans. These are easy to control, as this chassis comes with an included D-RGB adapter. Simply plug this into your motherboard, and you can control all your RGB through your favourite software such as Razer Chroma, MSI Mystic Light, and ASUS Aura Sync. Utilising this setup, create beautiful, unified lighting effects across all your components.
