Eurocard is an IEEE standard format for printed circuit board (PCB) cards that can be plugged together into a standard chassis which, in turn, can be mounted in a 19-inch rack. The chassis consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf.
The DTX form factor is a variation of ATX specification [1] designed especially for small form factor PCs (especially for HTPCs) with dimensions of 8 × 9.6 inches (203 × 244 mm). [2] An industry standard intended to enable interchangeability for systems similar to Shuttle's original "SFF" designs, [3] AMD announced its development on January ...

COM Express Mini PICMG: 2005 55 × 84 mm (2.17 × 3.31 in) Used in embedded systems and single-board computers. Requires a carrier board. Adheres to pin-out Type 10 [3] COM-HPC Size A
Other standards for smaller boards (including microATX, FlexATX, nano-ITX, and mini-ITX) usually keep the basic rear layout but reduce the size of the board and the number of expansion slots. Dimensions of a full-size ATX board are 12 × 9.6 in (305 × 244 mm), which allows many ATX chassis to accept microATX boards.
The four mounting holes in a Mini-ITX board line up with four of the holes in ATX-specification motherboards, and the locations of the backplate and expansion slot are the same [2] (though one of the holes used was optional in earlier versions of the ATX spec). Mini-ITX boards can therefore often be used in cases designed for ATX, micro-ATX and ...
DIN 41494-7 Dimensions of cabinets and suites of racks. DIN 41494-8 Components on front panels; mounting conditions, dimensions; DIN IEC 60297-3-100 (see above in IEC section) A rack's mounting fixture consists of two parallel metal strips (also referred to as posts or panel mounts) standing vertically. The posts are each 0.625 inches (15.88 mm ...
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
The rear panel aperture is identical to the EEB and ATX specification and expansion cards mounted on an SSI CEB motherboard appear much the same as they would on an ATX motherboard. To standardize thermal behavior, processor position is defined, including primary and secondary processor identification.
