This is an amazing case for a streaming/recording box + a gaming pc setup: http://www.lian-li.com/en/dt_portfolio/pc-d666/
It’s a single case designed to house two PCs. One is micro ATX, the other is full size. This would be so great for housing a fully-fledged monster gaming PC and on the other side a system designed for streaming or recording video from a capture card (e.g. low VRAM, high RAM, high CPU).
