The Source 340 comes with the standard accouterments that you would expect from a premium case, such as USB 3.0, filtered intakes, a PSU shroud, and quality materials and is easily one of the most durable cases we've ever made. A sea of space fills the interior, with the grommet less steel cable management bar splitting the front intake from the rest of the case and keeping cables hidden and tame. With 90% of the case being steel, we’re able to deliver superior durability for a case you can keep build to build. Comes complete with the basics, USB 3.0 and HD Audio, but gives you even more with high quality materials, a smart interior layout, and tons of cable management potential. We care about the little things. Steel plated audio jacks, captive thumb screws, and over twenty cable management points are just a few of the small touches that we’ve added.
