I should clarify, I'm speaking from experience, having built a 9900K system on top of an ASRock mATX board. The water cooling barely fit, and it pumps out heat like no tomorrow. Still, it's undeniably tiny and I irrationally love that build, which I can't say about my previous PC towers. So I'm probably the target market for this...
