Mother board dimensions

[abe7475]

Atx mobos come in several different widths. Approx. 7.5, 8.5, and 9.5 inches. I am reading in some mobo reviews that the narrower boards have an edge with no stand-offs under them making it more difficult to build (you have to be much more careful as to not damage the mobo when installing parts). Why the different sizes? Should I try to find a board that is the full 9.5 in. wide?

I think you meant depth. A Standard ATX has a depth of 9.6". Some of the smaller ones would have 7.5" and maybe 8.5". Though, I've never really used them. I have a Mini ITX that's about 6.5" and I know Mini ATX is at about 8".

If you really meant width, then I don't know any ATX motherboards with a width of 7.5" or 8.5".

Length, width, depth. Whatever you want to call it. To me depth implies 3 dimensions. The sizes that I see are 12 in. X approx. 7.5, 8.5, 9.5. The 12 in. is consistent. The others are not.

Yes; a motherboard is a 3D object so it has three dimensions -- width, height, depth. When calculating, you would have the motherboard with the peripherals slots in front of you. So going left and right (x coordinate) is width. Going up and down (y coordinate) is height. And going in and out (z coordinate) is depth.

Could you link to some motherboards of those sizes?
