Any motherboard with 200 series chipset will do. I would suggest finding one with either B250 or H270 chipset, no need for the more expensive Z270 without an overclockable CPU.
Next is just to find a mobo that fits M-ATX. Chose one from Gigabyte, Asus, MSI or Asrock with the features you like and within your budget. If you need help, please state your budget.
