With the 3770 non K version I am guessing overclocking is out. You have many board choices.
They have a pile of B75/Z77/H77 boards that will work with your cpu. Older H61/Z68 boards may also support the cpu(check the makers website to be sure).
I have a Z68 board that would work with that cpu(but is old enough that it would reduce the pci-e to revision 2.x not 3.0) and is MATX. They seem to have all kinds of board in mATX these days.
Make sure it has the features you want.
