Chenbro RM237 Series is a 2U enterprise server chassis. It acquires up to 17 patents for its modular and tool-less components. These Chenbro unique techniques optimize the time-consuming maintenance for users at data centers. Specifically, this model breaks the rule of upgrading server, discarding entire machine. Instead, users can only replace key components, including hard drives trays and cages, motherboard trays, fan cages, and add-in cards. Ultimately, these designs address the global issues of increasing e-waste, which is projected to continue at a rate of two million metric tons per year, caused by rapidly changing technologies.
