The ASRock OC Formula's Layout has been very well thought. Once more practical are the angled SATA connectors as well as the power- and reset-buttons. ASRock even equipped this board with a SATA Express connector as well as a M.2 slot which has been wired using two PCI Express lanes. There is also a debug display, which is always helpful if there are issues occuring with the motherboard itself or one of the installed components. Even the placement of the PCI-Express x16 is well chosen. There is a total of four of these slots and between two slots there is always an empty slot. We think this is a good number of PCI Express x16 slots for a overclocking/gaming motherboard altough most gamers will never use four graphics cards in their build. But still it leaves you with plenty of options if you want to plug in other expansion cards. Overclockers will also like the voltage readouts as well as conformal coating layer, which basically makes this board waterproof. In our opinion this board offers the best feature mix out of all Z97 boards we've had for testing so far.
