Doom 3: Project Mars City

Video games often inspire PC builds, but few cases are designed as meticulously as the Doom 3: Project Mars City. Built in the early-2000s around the release of Doom 3, the vision for this case was to create a structure that looked like it belonged in the Doom universe. The build started with a simple Antec case before evolving into something that looked like it had been magically conjured directly from the classic game into the real world.
We could write essays about this build, but creator Paul Capello did the hard work for us by posting his build log on the TheBestCaseScenario forum and uploading multiple YouTube videos (in 480p, so please excuse the top shot) that show the build from every angle. We encourage you to check those out for the high-res images—the level of detail is staggering.
