Say goodbye to visible cables – Concept PC parts from MSI, Asus, and Gigabyte eliminate cables by routing connectors to the rear of the motherboard.
Motherboards leading the way – MSI’s “Project Zero” motherboards and Gigabyte’s “Project Stealth” line already offer rear-connected motherboards, perfect for clean builds.
Graphics cards follow suit – Some new graphics card designs, like Gigabyte’s “Project Stealth,” draw power directly from the motherboard, eliminating the need for visible power cables.
So, yes, most of it is around cables, but cables are the messiest part of most PC builds today. It really does make sense for a complete rethink around cabling and cases.
