SILVERSTONE RM100 1U Rackmount case SST-RM100

The Silverstone RM100 is a compact 1U rackmount server chassis measuring just 44 mm in height, with an internal volume of 8 litres. It accepts ATX motherboards and is built from steel. Its external dimensions are 438 × 44 × 394 mm, making it suitable for standard-width server racks.

Inside, the chassis can hold a 3.5-inch hard drive cage and a full-size expansion card up to 270 mm long. Removing the 2.5-inch drive bracket makes room for a GPU up to 355 mm in length. The power supply can be up to 180 mm long, and this limit no longer applies once the 3.5-inch cage is removed.

The front panel provides two USB-A 3.2 Gen 1 ports at 5 Gbit/s. Cooling is handled by three built-in 40 mm fans at the rear. Direct access to the rear I/O panel of the motherboard is not supported in this design.
