As much as I agree with Cyril's belief that most desktops would be better served by smaller form factors, I have a soft spot for monster chassis and the gloriously excessive builds they tend to encourage. Lian Li's new PC-D600 looks like a pretty good example of the breed. This double-wide design accepts Extended ATX motherboards on one side and a stack of hard drives on the other. As the promo video reveals, there's loads of room for fans and liquid cooling radiators.
Splitting system components between two sides of the case should keep the windowed section free of excess cabling that might spoil the view. The case measures 15" wide as a result, but it's only 16" deep and 21" tall. Those dimensions produce a total volume that's only about 14% greater than the displacement of Corsair's Obsidian Series 650D mid-tower. The PC-D600 is roughly the same size as Corsair's double-wide Carbide Series Air 540.
While the Carbide sells for $130, the PC-D600 will be priced at $350 when it hits shelves on October 20. Of course, the Corsair case is made of plastic and steel, while the Lian Li is constructed entirely of aluminum. The PC-D600 also has more drive bays, fans, fan mounts, and front-panel USB 3.0 ports. I think it looks better, too, but that may be my old-school sensibilities talking—or my fetish for brushed aluminum.
Lian Li deserves credit for getting a lot of the little things right with the PC-D600. The case has integrated cable management clamps that can be moved around to deal with different routing configurations. The drive cages are removable, the side panel pops off without tools, and a single thumbscrew holds the entire front bezel in place. Then there are the filters, which can be found not only on the intake fans, but also on the vented drive bay covers at the front of the case. And, if you don't like the blacked-out motif, you can get the PC-D600 in silver instead.
The PC-D600 certainly isn't for everyone, but I'm glad beasts like this exist. If I were building a high-end system with multiple graphics cards, radiators, and a stack of hard drives, this case would definitely be on my short list.
