Phanteks Eclipse P400S Tempered black

This cabinet surprises with an interesting compromise from all sides. It's not huge, and it's almost everything you think. It is not the most expensive, yet it has a higher class function. Without much effort in the cabinet you will create a nice looking modern system. This computer house is so suited for beginners as well as more experienced builders who appreciate the extra features of expanding the computer set to the maximum. The innovative model boasts an exclusive transparent tempered glass side panel and RGB backlight with Asus Aura Sync support.

Key features

  • User-friendly, spacious cabinet
  • Design with lower noise
  • Stylish look + RGB backlight with Asus Aura Sync support
  • Large transparent sidewall made of tempered glass
  • Position for 5 fans (2 mounted)
  • Support for water cooling
  • Complete system of dust filters
  • Frequently used handheld connectors

Dream set in available class

In this case, you almost do not need to be limited in any direction, even if it falls into the Miditower category. As the foundation stone of a new computer, you can choose the motherboard among the largest eATX format, which is rewarded by the larger interface equipment for further expansion. The graphics card limit is up to 395 mm, so it can be reached even in game pieces. The space for max. 6 drives (including 2 spaces) must be rich enough for most users and more demanding consumers.

Reliable heat dissipation

Do you want to give your hardware the right environment? The 3 large filter system successfully prevents dust from entering the interior. The fans are kept clean, and the cooling is then more efficient and quieter. You can reach the water cooling where it supports up to 360mm heat exchanger forward and 120mm backwards. With powerful cooling, the problem will not increase the CPU ,or graphics frequency.
