Every Hidden Advantage of Every Motherboard Size EXPLAINED!

That smart panel on a hotel wall. The screen at a parking gate that reads your license plate. There's a computer inside both of them — and it's almost certainly running on a motherboard the size of a credit card. From boards so small they sip power off a solar panel, to ones built specifically to hold two physical CPUs and a terabyte of RAM, every motherboard size exists because it solves a problem no other size solves quite as well. In this video, we break down all twelve motherboard form factors — what each one is actually built for, where it shows up in the real world, and why "biggest" or "smallest" almost never means "best."
