Thank you for the video. I was a big fan of Dreamcast. It's a pity that the project was failed and Sega left the console marketplace. However, as we saw in the video Dreamcast is alive nowdays : )
About my cases I want to say that this is a platform for building a special type of PC ― HTPC. I think, there's a sense to check them if you want to build a home entertainment system. Yes they have a good and attractive design but we mustn't forget about the price ― it's many times expensive.
