Hi at all,

i want to buy a certain mainboard
it´s the ASrock Z170M Extreme4

http://www.asrock.com/mb/Intel/Z170M/Extreme4/

Unfortunately there is only the information microATX on the website and the pdf file.
no exact mm or inch info!

But i need to know exact dimension in mm.
on wikipedia there is the info. micro-ATX: 244 mm x 244 mm (9,6 inches x 9,6 inches )

my current mobo is an intel DG31GL MicroATX
http://ark.intel.com/products/35120/Intel-Desktop-Board-DG31GL
The Technical Product Specification pdf says
MicroATX (9.60 inches by 8.60 inches [243.84 millimeters by 218.44 millimeters])

My case has no place für 244x244 mm boards 


Thank you for any input
