Didn't you already have a thread about this?
Micro ATX and ATX have the screw mounts in the same places.
The only other question is whether your case has the physical space.
(The only difference between ATX motherboards and Micro ATX motherboards these days is just the number of PCI slots.)
So I mean, if you want to know if you can use ATX for more choices, the only real difference is extra PCI slots? Other than that, ATX and Micro ATX are the same.
I don't see why you'd want an ATX motherboard unless you have a lot of PCI cards or something.
Micro ATX boards are cheaper and offer the same options.
[I want to clarify why no one can give you an exact answer]
1: You're not giving us enough information about your case.
2: You're asking us if a quarter can fit in a hole, just because a dime can fit in said hole.
(Dimes can fit in smaller holes than quarters can.)
Micro ATX=Dime
ATX=Quarter
A dime can fit in a hole that can house a quarter easily, but the same can't be said the other way around.
So we can't tell for sure unless we know the dimensions of your case, that's pretty much the only question.
Your case has the proper screw mounts, if it can has Micro ATX, it's a question of size/dimensions.
