Someone managed to cram AMD's Ryzen 7 1700 and a Radeon RX 570 into Streacom's black monolith using the 4 side panels, for the first time ever. And temperatures are pretty good! Interestingly, the fanless cube was designed to use its four panels when we premiered it four years ago. The black DB4 is available now from Quiet PC.
