Will an atx motherboard fit my case?

[weedface]

i have this computer but i can't find anything on my case and I'm wondering if a regular atx motherboard will fit in it.

if it can't could someone show me a cheap but good case?

That case's dimensions are well above ATX. I'm pretty sure it can house an ATX motherboard, but we can't be sure unless we can see the screw holes.

You can always get an Antec 200 for about 50$.
