Compact Electronics Bay Specification ( CEB ) is the standard form factor for dual-processor motherboard, which of the Server System Infrastructure ( SSI) forum defined (specified) is often written as an abbreviation or N- grams SSI CEB. The SSI CEB specifications are primarily intended for server computer cases, motherboards, power supplies, and other server computer elements around the motherboard. An SSI CEB motherboard has the dimensions 305 mm × 267 mm ( 12.0 inches x 10.5 inches).

The SSI CEB specifications were developed from the EEB and ATX specifications. SSI CEB motherboards have the same IO port unit and often the same motherboard screw holes as ATX motherboards. The connection level for plug-in cards is the same as for ATX motherboards. However, SSI CEB motherboards are generally larger in dimensions than ATX motherboards and often have other CPU - mounting base, and mostly as a dual CPU ( dual ) or quad- CPU ( four times) motherboard running uniprocessor ( single - CPU) models much rarer.
