I did write a long answer but the page here changed to a "Accessed denied"
and everything got lost. Here is a shorter version.
Product specifications.

I know that Asus Z97I Plus works except wifi and bluetooth. Displayport,
HDMI, DVI-D and VGA works. Network, audio, USB3 internal and external ports,
SATA3. Everything integrated in Intels chip works. Sabertooth Z97 Mark 2 has
the same network chip so that will work. Search on Realteks page or search
the net and see if the Realtek ALC1150 works. Same with the extra ASMedia
USB3 ports work. Look around if you can get the information on bluetooth and
wifi chips and see if they are supported.
Search at h-node.org. If you find information about a product on the net if
it works of not, add it in the h-node database to help other people in the
future.
