I've looked around with Google, and the best I can find is templates for the motherboard styles that have come out in the last few years. Unfortunately, the motherboard I have and want to use for a case mod project is an M2N61 AX from an older Dell. Anyone happen to know a place that has templates for laying out where to drill the mounting holes for that motherboard?
Your mobo was made to go inside a Dell Inspiron 530. According to this site, the mobo is a MicroATX form factor. So if you follow this diagram, you should have your hole placement: Fair warning: I've never worked with that specific type of mainboard, so verify before you start drilling mounting holes.
Thanks, that actually looks pretty close to what's in there. It's fairly close to the dimensions I got just from eyeballing it with a ruler.
