Caixa de PC Jonsbo RM2 Prateado ATX ITX micro ATX ventoinha 120mm

RM2, released by JONSBO in mid-2015, is a compact aluminium PC case that supports ATX, micro ATX and ITX motherboards. Constructed from magnesia-alumina (aluminium alloy) with a smooth wiredrawing finish, the RM2 uses a unibody U-type main body and a 360-degree rounded exterior. The design accommodates dual-slot graphics cards up to 290 mm and crossfire configurations while keeping a compact footprint (209 mm W x 302 mm D x 341 mm H). The case includes space for one 3.5" HDD and three 2.5" SSDs, two front USB 3.0 Type-A ports and supports 120 mm front cooling fans.

Advantages

The RM2 combines full-metal construction and precise wiredrawing surface treatment for a durable, consistent metallic appearance. Its unibody build and hidden fasteners produce a clean exterior without exposed screws on the top, front or sides. Despite its small size, the case supports standard ATX motherboards and dual-slot graphics cards up to 290 mm, offering greater upgrade flexibility than many compact cases. Integrated front USB 3.0 ports and dedicated drive bays provide practical connectivity and storage options.

Suitable for

• Compact desktop builds that require ATX, micro ATX or ITX motherboard compatibility
• Systems using dual-slot graphics cards up to 290 mm or multi-GPU (crossfire) setups

How to use

Install the preferred motherboard (ATX, micro ATX or ITX) into the pre-drilled standoffs, route power and data cables through available openings and mount storage drives into the dedicated 3.5" and 2.5" bays. Fit a dual-slot graphics card up to 290 mm in length into the PCIe slot area. Connect front-panel USB 3.0 ports to the motherboard header and install 120 mm fans in the front if additional airflow is required. Use the integrated unibody structure to align panels and conceal fasteners during assembly.

Recommendations

The RM2 is best used in environments where a compact aluminium chassis with ATX compatibility and discreet exterior is desired. For adequate cooling in high-performance builds, install at least one 120 mm front fan and ensure unobstructed airflow around the GPU. Verify GPU length and PSU clearance before final assembly.
