If you have to ask what it costs, so the saying goes, you can't afford it. With this mammoth PC case from Corsair, consider a corollary to that: If you have to ask why, you probably don’t need it. This is the best advice, as seasoned reviewers, we can give for Corsair's staggeringly over-the-top 9000D RGB Airflow. This $499.99 chassis, capable of hosting a full-size PC and a Mini-ITX system inside, supports up to four 480mm (!) radiators without even considering its 360mm and 240mm mounts. And of course you’ll want to fill it with two motherboards, two power supplies, and two graphics cards because…why not? Needless to say, this mega-chassis could be all about the bragging rights, but you'll need plenty of space to spare and dough to blow to consider this titan your next case. Streamers with a need for both gameplay and game-capture machines in one chassis, or video editors who want to have their editing and rendering rigs in one enclosure might consider this beastly box. The 9000D is great for that niche and wins an Editors' Choice award for being the ultimate twin-rig chassis, but is it ever imposing.

To say that the 9000D is bigger than big should be descriptive enough for most folks, but if you're sitting around imagining what you might do with practically unlimited mounting space, we'll have your attention now. At 27.5 inches tall, the case is too tall to fit under any desk we've ever owned, and too heavy (66 pounds empty!) for some desks to support, too. Size alone differentiates its aesthetic from your typical glass-sided steel gaming case. This thing is simply a monster. (It's almost exactly as deep as it is tall, too.) You can get it in white or black versions.
