The main difference between the ASUS GR701 ROG Hyperion and the ASUS GR701 ROG Hyperion BTF Edition is the support for the "Back-to-Front" (BTF) design. While the standard model is an advanced EATX chassis, the BTF Edition is specifically designed for motherboards and graphics cards with hidden connectors, resulting in a cleaner and cable-free build.
ASUS GR701 ROG Hyperion (standard model)
A premium EATX case known for its material quality, performance and integrated RGB and fan control.
Provides comprehensive support for heatsinks and components.
ASUS GR701 ROG Hyperion BTF Edition
This model builds on the GR701 and adds the ability to use motherboards and graphics cards with the connectors hidden at the rear.
This enables an almost completely cable-free PC design.
It is the ideal solution for users who value a particularly tidy aesthetic.

the difference lies in the rear panel, the BTF version has more cut-outs than the normal version. you can see the differences between the cases in a google search.
