Questions about this item

Will this motherboard fit a standard ATX case and align with the I/O cut-out?

The board uses the ATX form factor so it mounts in any ATX case, but the listing notes that no I/O shield is included so you will need to reuse the original shield or source a compatible one separately

Which processors can I install and what memory speed will they run at?

The LGA 1151 socket accepts 8th and 9th generation Core i7, i5 and i3 CPUs; the two 288-pin slots support DDR4 2400 up to a total of 16 GB

What expansion slots and rear ports are available for a graphics card and peripherals?

One PCI Express 3.0 x16 slot takes a graphics card, one PCI Express x16 and one Mini PCI slot provide additional expansion, while the rear panel offers one HDMI, one RJ45 and four USB 3.0 ports
