Is this Rev 1.0 or Rev 1.1 of this motherboard?

I never purchased that motherboard! I went with an Asus motherboard... Sorry I couldn't have helped...

Will it work with Ryzen 9 5900X 12-Core 3.7 GHz?

Yes, the GIGABYTE B550M AORUS PRO-P AM4 Micro ATX Motherboard supports AMD Ryzen 5000 Series processors, including the Ryzen 9 5900X 12-Core 3.7 GHz.

Will it work with Ryzen 9 5900X 12-Core 3.7 GHz?

Yes, the GIGABYTE B550M AORUS PRO-P AM4 Micro ATX AMD Motherboard supports AMD Ryzen 5000 Series processors, which includes the Ryzen 9 5900X 12-Core 3.7 GHz processor. However, a BIOS update may be required.

will this fit the NR200p?

No. The Cooler Master NR200 series of cases can only fit Mini-ITX motherboards. Micro-ATX is too big.

Does it have an ARGB header?

Yes, it has 2 addressable LED strip headers.

Is there a difference compared to the B550M AORUS PRO?

Upgraded VRM's, slightly downgraded audio codec.

Never had a Ryzen build. If I buy a Ryzen 5 5660 or Ryzen 7 5800 and put this in, is this motherboard good to go?

Depending on build date you might have to update the BIOS first. Luckily this board lets you do that WITHOUT a CPU installed.
