Will need your vender to give you some options. I use a biostar th55b hd micro atx board with 4 dimm slots and some overclocking options. It doesn't have usb 3.0 or sata 6.0 like some of the newer boards, but it works ok. Frys.com had an msi h55 board the other day for only $45 after rebate, but sold out online. It's still available in some of their stores.
