- Audio and Networking: A decent onboard audio solution was important for my gaming and media consumption. I also wanted a reliable Ethernet port for stable internet connectivity.

I set a budget before diving into the options. Micro ATX motherboards can range widely in price based on features and brand. I found that spending a little more on a reputable brand could save me from issues down the line, so I didn’t shy away from investing in quality.
