If you want cheap, no thrills no frills with SATA3 & 16gb memory support, the Asrock B75M-GL
mobo is good for a micro atx. Or if you don't like the small mobo's then you could go with a Asrock Fatality P67
which was recommended by Tom's.
Edit: IMO, 16gb is overkill. you could save some $$, drop down to G.Skill Ripjaws X Series DDR3 1600
for $35 and step up your GPU or CPU.
