GEOMETRIC FUTURE Reveals Expandable Model 4 King Arthur Compact ATX Case

GEOMETRIC FUTURE is a newer manufacturer founded in 2020 and is behind some rather interesting case designs including their recently launched Model 2 Ark and today their Model 4 King Arthur.

Model 4 King Arthur

The Model 4 King Arthur, aside from its odd name choice, is a compact ATX case that overall sticks to the standard designs we expect to see from cases, but opts for an odd split design front panel with mesh on the lower half and solid on the upper half. The reasoning for this design choice is that the case uses the PSU format of many ITX and compact cases where it is mounted on the upper right corner due to space constraints. This design has led to a bottom-to-top cooling design with rising heat.

The lower half of the case features vents across the sides for drawing the air through the bottom where it rises to the top through the ventilated L-shaped one-piece side and top panel. This side panel and top fan bracket can be expanded upwards to provide more space for radiators in the top of the case.

Cooling Support

The Model 4 offers room for up to 9 x 120mm fans or 3x 120mm and 4x 140mm and for water-cooling it allows for 240mm and 360mm in the top and bottom respectively.

Hardware Compatibility

The case allows for up to E-ATX motherboards with 164mm of tower cooler space, 405mm of GPU clearance and 180mm of PSU when vertical and 150mm horizontal. For storage there is room for two 3.5″ drives and four 2.5″ drives which is more than some full-sized cases.


  • Expandable and modular frame support two installation modes
  • Compact ATX Mid Tower at only 35L
  • Mesh footstand supporting 3x 120mm/ 2x 140mm fans
  • L-shaped top/side panel

  • Supports ITX to E-ATX motherboards
  • Compatible with 240/360mm radiators
