RM2 is made from complete magnesium-aluminum oxide material. The design style continues with a sense of elegant, simple streamlining and strong metallic elements. Unlike the right-angle design of the previous U-series, RM2 features an innovative 360-degree design in round packaging. It supports not only dual-slot graphics cards within 290 mm but also CrossFire graphics cards, providing users with a powerful mini platform. The entire outer shell of RM2 is made from 1.8 mm magnesium-aluminum oxide alloy material. The Jonsbo team has extensive experience in wire processing of anodized surfaces, featuring two high-speed USB 3.0 interfaces, gold-embossed wire-drawing feet, metal CD texture buttons, and a heavily built unibody U main body with integrated nail burying. There are no visible screws on the top, front, or sides. With RM2, users have a great opportunity to upgrade and expand their machines. Due to high raw material costs, conventional full aluminum ATX cases are very expensive. Because of their small size, they typically do not support standard ATX motherboards. There are many limitations for users looking to expand and upgrade their systems. RM2 allows traditional users to experience the concept of integrated furniture design and the metallic texture advocated by Jonsbo. Additionally, DIY enthusiasts can choose from more motherboards and graphics cards.
