4U rackmount chassis for SSI-EEB builds

The Silverstone RM42-502 is a 4U steel server chassis that accepts SSI-EEB, SSI-CEB, Extended ATX, ATX, Micro-ATX and Mini-ITX motherboards. It provides seven expansion slots and can be mounted in a rack or used upright on a bench. A front-panel anti-theft lock and a side intrusion switch add physical security for shared environments.

240 mm liquid-cooling support at the front

The front panel fits two 120 mm fans (one included) and a single 240 mm radiator, while the rear offers two 80 mm mounts (one fan included). CPU cooler clearance is 148 mm without the GPU holder fitted and 130 mm with it installed. A PS2/ATX power supply up to 442 mm long can be used alongside the 5.25" devices.

Suits rackmount servers needing front USB-C

Builders who need front-panel USB Type-C, two 5.25" bays that also take 3.5" or 2.5" drives, plus an internal 2.5" slot will find the layout convenient. Those requiring more than seven expansion slots, larger radiators, redundant mini power supplies as standard, or tool-less drive trays should consider other chassis.

Questions about this item

What SSI-EEB motherboard size fits in this 4U chassis?

The RM42-502 supports SSI-EEB, SSI-CEB, Extended ATX, ATX, Micro-ATX and Mini-ITX motherboards, so a full SSI-EEB board fits without modification.

What front-panel I/O ports does the USB Type-C interface sit alongside?

The front I/O includes one USB Type-C, two USB 3.0, one audio and one microphone jack, all accessible behind the lockable front door.

How much depth is left for a power supply when the 5.25" bays are populated?

With PSU and optical drives installed the maximum depth is 442 mm, so choose a PS2 (ATX) or mini-redundant unit that stays within that length.
