MicroATX Mounting Hole Positions

This is a basic layout for MicroATX motherboard mounting holes.

I was trying to design a microATX PC case and did some research for exact standoff locations.

If you are trying to design a PC case with a Micro ATX or even (i believe) an ITX, then you can use this template to find your standoff locations and just lay it over your design to perfectly line up your mounting holes.

This is designed using the exact specifications in the microATX Motherboard Interface Specifications V1.2.

Includes all mounting holes B, C, F, H, J, L, M, R, S.
Holes R and S are specifically for the microATX form factor. R should be used (with S being optional) if it is a full sized microATX form factor (244mmx244mm). For boards narrower than 244mm, of the two holes R and S, only hole S is optional.

Hope this helps someone!

PS: The standoff file is not printable on it's own (well you can but you would just get a bunch of small towers). It is meant to be used in conjunction with a design where a microATX motherboard needs to be mounted. The files marked standoff tray is printable and is just a basic board with the stand offs aligned in place.
