As a counter to this, my local Micro Center is absolutely booming. I built a fast gaming machine earlier this year, and found all of my desired components in-stock there, with no compromises. Their prices were identical to the lowest prices online, and they offer price match anyway. All of my Ubiquiti stuff I got there as well. They have an expanding hobbyist electronics section that consumed the old physical software/gaming space. They have other great hobbyist stuff like retro gaming and drones. I've just taken it for granted, not realizing that many people consider Micro Center a PC builder "Mecca".[0]
