SilverStone RM51 5U Rack Case, Black (SST-RM51)

The 5U Silverstone RM51 rack enclosure is designed for industrial rack mounting or high-end home systems and can be positioned either vertically or horizontally.

The enclosure is equipped with two pre-installed Air Penetrator 184i PRO fans, ensuring excellent cooling performance. It is backward compatible with 3 x 120 mm fans, allowing for either triple 120 mm or dual 180 mm liquid cooling.

An internal 3.5" drive bay allows for the installation of 2 x 3.5" HDDs. If left empty, it allows for the installation of a secondary power supply in SFX format. To prevent unexpected damage to the motherboard or graphics card, it includes an expansion card holder with storage mounting holes that prevent graphics cards from sagging and maximize space utilization.
