The Elite 333 has four exposed 5.25" drive slots, 2 exposed 3.5" drive slots, and 5 hidden 3.5" slots. The slots do not require tools to access, so installation and upgrading are simpler. The Elite 333 includes a built-in washable front air filter, and a spot for an optional 120mm front fan. The case is compatible with ATX and micro-ATX motherboards, and stylistically different from the other Elite 330 models.
