How about this one?

all the cheaper boards are Dual Channel. There's also no advantage to Quad Channel unless you've got a much higher-end CPU and even then only under certain applications.
If you want 16GB of memory, just get a 2x8GB kit and use the recommened slots (possibly #2 and #4) as per the manual.
Populating ALL the slots just means each set is in Dual Channel. So 4x4GB is the same as 2x8GB for performance and capacity.
See partpicker but I'd get a 2133MHz CL9, 2x8GB kit. maybe CORSAIR
Update: wrong kit....
