There does not seem to be much difference between the newly announced Special Edition H440, "Designed by Razer", and the original. The announcement claims: a custom paint design, LED lighting, a tinted window, and more. The design includes four fans (3x 120mm and 1x 140mm) and supports water cooling radiators up to 360mm.
By the specifications, nothing is different, functionally. That said, when you are dealing with a company who will budget out hundreds of thousands of dollars in research and development for a USB port color, it is entirely possible that a few screws might have moved slightly, and so forth. Then again, the images on the product pages seem fairly identical. Speaking of Razer's expensive USB ports, it looks like the USB 3.0 ports are that shade of green. Call it, "Extending their return on investment"?
Annnnd of course, no pricing or availability. That is, apart from: "Coming Soon".
