Phoronix is usually a good source of info on linux hardware and has quite a few m/b reviews.
I just set up a Gigabyte micro-ATX board. The only problem was the Realtek audio. Eventually got it working by playing with the driver options listed in the kernel docs - added line
options intel-hda-audio model=6stack-hp
to /etc/modprobe.d/alsa-base.
