Difference between Micro ATX and Flex ATX?

[oniq]

Is there a difference between Flex ATX form factor and MicroATX form factor? I've been on sites that when I searched for Flex ATX it brought me to MicroATX motherboards. Any ideas? Thanks in advance.

Yes, there is a slight size difference...if I remember correctly, Flex is in between micro and ATX. I have the exact dimensions at work, but I'm not there now. I could send the info, or do a search for "atx mounting hole layout".

isn't the difference that flex atx dosn't use cards and micro atx does but has fewer slots?

MicroATX is larger than FlexATX. A typical microATX board will have up to four expansion slots (PCI, AGP and/or other types). I don't think FlexATX can have more than three. A FlexATX board should fit a FlexATX, MicroATX or regular ATX case, unless it is a fully-proprietary design or something. I think there are other differences too, such as the permitted CPU socket location. I have seen FlexATX mostly being used for BookPC's.
