With dozens of affordable, well-equipped desktop cases begging for your cash, it can be a nightmare to find the right one for your needs. Hoping to simplify your building experience, we've assembled a shortlist of six unique sub-$200 enthusiast chassis that deserve your attention.Included in our roundup is BitFenix's flagship Colossus, which takes lighting to the next level courtesy of multi-color LED strips that embrace the enclosure if that's your kind of thing. We also have the company's new Shinobi mid-tower, a budget-minded gaming chassis with a bold yet clean design. Announced earlier this year, the Cooler Master Storm Enforcer is an attractive and surprisingly affordable addition to CM's extensive chassis lineup. The company boasts that it's the first mid-tower with native support for massive dual-GPU cards like the Radeon HD 6990 and GeForce GTX 590. Cooler Master's acclaimed HAF X has also come along for the ride, and this time we have an in-your-face green edition that will surely test the gag reflex of Radeon fans. Despite its flagrant lime green frame, the HAF X Nvidia Edition is essentially the same case we've come to know and love.
