XTIA “Butterfly” Structure
The specially designed intermediate mezzanine (Zone C) can be used as a cable management area and also contains a hard drive mount point.
The Butterfly design provides high structural integrity and an aesthetically pleasing modular design.
Three Segment Case Assembly
Zone A: PSU & motherboard
Zone B: GPU & power switch
Zone C: cable caddy, hard drives
Modified Open “Sandwich” Case Layout
The open chassis has much better heat dissipation, leading to improved gaming performance. Because of better thermals for your components, you can dial down your fan curves to keep noise at a minimum. It also negates any noise-creating turbulence caused by side panels.
The open-air layout has no dead corners for dust to accumulate, and any dust can be easily cleaned off.

Fully CNC Machined
The case is CNC machined from thick, sturdy 4mm aluminum panels, allowing the case to be both lightweight and steady.
The case is a nearly unibody design, allowing for easy assembly as well as elegant rounded corners.
