ECS brings a cheaper Z270 option for Mini ITX builders. Does the board offer the overclocking potential worthy of its PCH? Intel promotes the Z270 as the highest-model option for its mainstream LGA 1151 socket by enabling most of the features available on its silicon, yet most of those features won't fit into a Mini-ITX form factor. You won't, for example, run CrossFire or SLI across two cards on a board with only one slot. Overclocking becomes the prime reason to choose Z270 over H270, and even then we?re often stuck with the small voltage regulators that fit within the shorter depth of Mini-ITX.
