2015 was undoubtedly an intriguing year for computer cases. That was the year HotHardware gave away a CyberPower Trinity Xtreme PC, which had three separate chambers. AMD also had their interesting design with the Project Quantum PC. The PC was designed to be “the VR PC of the future” with a complete redesign from the ground up. It was a small form-factor device with a split chamber setup. The bottom chamber would house water-cooled components, and the top section is where the heat would be exchanged. The goal was to showcase AMD’s 2015 graphics horsepower in as small of a space as possible. AMD posted a video at the time of the device’s engineering, which you can see below.
After the video came out, really nothing was heard of the Project Quantum device. It was presumed that the project had been killed off in favor of other projects AMD wanted to take on. The patent that @Pete_2097 stumbled upon was granted on September 15th and likely was buried by the virtual train wreck that has been going on during 2020. Inside the patent are some design sketches which look nearly the same as the device we saw in 2015.
