4U rackmount chassis for CEB motherboards

The Chenbro RM42300-F1 is a black steel and plastic 4U rackmount server chassis designed to hold CEB form-factor motherboards measuring 12 by 10.5 inches. It provides seven expansion slots and a single 120-millimetre fan installed, with support for up to three fans in total. Front access includes two USB 2.0 ports for local management.

Suited for dense storage builds.

This chassis fits environments that need up to four internal 3.5-inch drives, three external 5.25-inch bays, one external 3.5-inch bay and one external slim bay in a 4U footprint. Builders requiring redundant power supplies or more than seven expansion slots should consider alternative enclosures.

CEB motherboard compatibility defines fit

The decisive specification is support for CEB motherboards at 12 by 10.5 inches, which determines whether your server board will mount correctly in this 4U rackmount chassis.

Questions about this item

What fan maintenance does the RM42300-F1 require over time?

One 120mm fan is installed and the chassis supports up to three fans, so additional units can be added or the original replaced as needed.

Which constraint appears first during continuous operation in the RM42300-F1?

Only one 120mm fan is fitted from the factory, so airflow capacity is the first limit under sustained load.

How much noise and heat should I expect from the RM42300-F1 running all day?

A single 120mm fan provides baseline cooling; acoustic output and internal temperature will rise if all seven expansion slots and ten drive bays are populated.
