The Corsair Obsidian 1000D is, hands down, one of the biggest and baddest PC cases to come out in recent years. With room for two complete systems, up to five graphics cards, two 480mm radiators in front and another 420mm up top, there’s no other chassis on the market that can hold more components.

Aside from being a monster case in size and capacity, Corsair employed a bunch of new features with its latest Obsidian case, including liquid-cooling drawers and French doors to hide all the PC power cables – and even six SSD trays.
