The RM237 series by Chenbro is a 2U enterprise server chassis featuring a modular design with components that can be added or removed without having to resort to tools. Important parts – such as a hard drive and the motherboard trays, fan cages or add-in cards – can be exchanged when the capacity is to be expanded or technically more advanced hardware added. In this way, the server chassis may be utilised over an extended period of time, which also helps to prevent electrical waste.
