Hi!
I wonder how to find out if my motherboard is ATX or not, cause I'm buying an new midi tower for my PC and I wonder if my current motherboard will fit in to it...

Try going to www.belarc.com/download.htm

There is a free download that will give you a comprehensive listing on everything in your PC. This listing is invaluable in getting tech support.

It will list the brand and model of your motherboard. If it deson't mention if its ATX or not, you can use that info to check the manufacturer's web site for the info.

If the computer is 3 years old or newer, then it is a safe bet that it is definitely ATX. Just to make sure, open up the pc's case and look at the power supply and it will have either AT or ATX on its side label. Problem solved.

Just go to the manufacturer of the Mobo you have and didn't you get any booklets with it, or a box.
