Motherboard Sizing @ LanOC Reviews
 

When we got in a few oddly sized dual CPU motherboards from EVGA and Asus I posted up a few pictures on our forums and on Facebook. The problem was that even though they looked large there wasn't any prospective. So we tossed in a couple other boards to give everyone a little perspective. This lead us to digging out even more motherboards to put together all of the standard motherboard sizes all together for everyone to be able to see the differences. Along with the picture we also have a breakdown on the dimensions of each size standard; I hope this helps everyone as some point. Sometimes it can be hard to understand all of the different motherboard sizes and how they all relate.
