Cobalt Qube

The Cobalt Qube was a computer server appliance product line, meant to be web servers, developed by Cobalt Networks, Inc. (later purchased by Sun Microsystems) from 1998 to 2002 featuring a modified Red Hat Linux operating system and a proprietary GUI for server management.

The original Qube systems were equipped with RM5230 or RM5231 microprocessors but later models used AMD K6-2 chips.

NetBSD operating system has been ported to both the Cobalt Qube and RaQ.

But, released in 2000, was eventually called the Qube 2, leaving the 2800 to designate the system type.

The casing featured on these units was black instead of cobalt blue.
