SilverStone's latest slim Mini ITX case reduces the thickness required for graphics cards by laying the slot sideways. As shown in the first photo, second photo shows what it looks like inside.
Includes the PCIe 4.0 x16 riser cable, stands to keep it upright, stick-on feet for anyone who wants to lay it on its side, and an installation kit for screwing in your components. Available for pickup in the nice neighborhood behind CMU campus, north of The Cabin.
