Where can I find the EATX Specifications?
I'm looking for the motherboard specifications for Extended ATX motherboards (e-atx). Please do not point me to formfactors.org; they have ATX specs; I'm looking for EATX, more specifically, the screw hole placements for the larger, 12"x13" boards. I'm building a case from scratch and need this. Any help would be appreciated!
From Scott Mueller's "Upgrading and Repairing PCs", page 216 in my version (16th ed):
"Some mobos, esp those used in server systems, come in nonstandard ATX variations collectively called extended ATX." (there's more, it's a side note)
Since it's nonstandard, you'll have to find the exact board you want to build for, and find out its screwhole locations from the seller or manufacturer.
