First ever build, help picking a micro ATX motherboard?

My aim is to build something mid range with aesthetically-pleasing components for gaming, mostly. I'd prefer the motherboard to be white or light silver, but I'm reading mixed reviews on everything so it's hard to pick one. I'd prefer to stay around $200 or under on it.

Here are the components so far, in case anyone has cool tips they'd like to share on building with them:

I went with the Thermaltake Tower 300 in hydrangea blue (super excited at how beautiful the color and style is!)

Gpu is a Yeston AMD RX 7800 XT 16gig

Got a Ryzen 7700 CPU

Super Flower Leadex III in white for the PSU

Predator 2TB SSD for storage

32gig Teamgroup DDR5 Ram

Also, any estimate on how many fans I'll need to keep things cool? The case comes with two fans and the CPU has a built in cooler

I'm super new to this stuff and trying to do things the right way with this build, so any tips are super welcome!
