GIGABYTE - B550 I AORUS PRO AX AM4 USB3.1 AMD Motherboard - Small Form Factor - Black

It does came with a built in wifi card that has an attachable antenna with a magnetic base and 4 different positions so it can be placed really anywhere on the case. I put mine on the back of the case so it can’t actually be seen from the front, although I’m using the Ethernet port, it maybe better on top of some systems depending on where your router is if you’re only using wifi. I hope this helps!

5300 MHz. But I feel like anything over 3600MHz is overkill. I believe the Ryzen processors only officially support up to 3200MHz.

heck yeah dude, it even has a little heatsink for it so it won't get to spicy during use source: specs and reviews

Hi BIZKeT, The MB ships with the latest BIOS from the time of manufacture date. These will have the bios to support Ryzen 5000 series out of the box. Hope this helps! - John

Hi Dan, Yes this will work just fine with the Stock CPU cooler and most 3rd party coolers. We spaced out the memory so that there should be no interferance except for the biggest of air coolers. Hope this helps! - John
