Geometric Future Model 4

The Model 4 user guide lists 1.0 mm and 1.2 mm steel panels with 3.0 mm tempered glass, not a predominantly aluminum exterior. Some catalog descriptions therefore overstate the aluminum construction.

The case supports E-ATX up to 12 by 11 inches, ATX, Micro-ATX, and Mini-ITX boards. It is therefore a compact mid-tower with more board support than a typical small-form-factor case. [Model 4 user guide](https://www.geometricfuture.com.cn/uploads/file/Model%204%20User%20Guide__.pdf)

The guide lists a 240 mm top radiator in lifting mode, a 120 mm rear radiator, and a 360 mm bottom radiator. Fan support includes two 120 or 140 mm fans at the top and up to three 120 mm fans at the bottom. [Model 4 user guide](https://www.geometricfuture.com.cn/uploads/file/Model%204%20User%20Guide__.pdf)

The guide lists graphics-card space under 405 mm long and 168 mm wide, while the CPU cooler height limit is under 164 mm. Vertical graphics-card mounting has an additional thickness limit of under 50 mm when the bottom-fan condition applies.
