Just because its new doesn't mean it has to change sizes. Like the Source 210 and the 210 Elite. The elite has USB 3 and its the newer version
Who said anything about sizes, I do wish people would read posts before replying to something that wasn't said.
There was the HAF XM, but that's a smaller version of the HAF X. There was also the HAF 932/ HAF 932 Advanced (HAF X is also known as HAF 942), which added a kludgey front panel USB 3.0 connector box. There's also the HAF X Nvidia Edition, but that's just a different color.
