No confusion about chipsets. Choose a low feature z77 chipset board. I use msi, asrock, or biostar, but my current board is asus. Those boards are around $100, which is affordable. Simply pick one with the ports and slots you need. And don't go cheap on the power supply. 550-600 watts should do it; antec, corsair xfx, seasonic, enermax, and ocz are some of the brands I've used.
