ABSTRACT:
A dual-board case for multi-mainboard system includes a rectangular-sectioned tubular housing, in which two track sets are provided; and two mainboard trays being movably mounted on the two track sets to locate at an interior of two opposite lateral walls of the tubular housing. Each of the two mainboard trays has a loading surface, on which a mainboard is mounted; and the two mainboard trays are mounted on the track sets with their loading surfaces and accordingly, the two mainboards mounted thereon facing toward each other. Therefore, the dual-board case allows a multi-mainboard system to have optimal spatial arrangement to achieve best heat-dissipation efficiency and largely reduce noises.
