Asus p8p67 pro motherboard
Also, just a rule of thumb. If a motherboard has 2 or less PCI slots, that includes 1 PCI-Express fullsize slot and 1 PCI-Express 1x, 2x, or 4x, its usually micro ATX. ATX or Extended ATX boards tend to have 4+ PCI slots. I haven't seen a normal ATX board with less than 3 slots.
