My question is about computer cases.

ATX Form Factor? What are the standards?


I am looking at purchasing a Lian Li PC-X900 case and it says its form factor is ATX. Now, I read many advertisers sites and some say the form factor is 12 X 9.6 and others say the form factor is 12 x 10.6. So which is it?

I want to purchase the Asus Rampage III Extreme or the Extreme Black Edition but Asus says its ATX Form Factor @ 12 X 10.6. I just need to know if this mobo will fit in my case.

Thanks!

Peace.
