Basically 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. There is also a debug display, which in this case features a high resolution display. 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 and we're quite sure overclockers will really enjoy the conformal coating layer, which basically makes this board waterproof.
