Out of curiosity. How does one power a case on or off without a power switch?
I think the top mini itx case isn't really meant to be used for a chassis, and more of a radiator area to stick loads of rads in. But it does have support for mini itx mobos.
I guess then you could Dremel that nice CM logo out of the front panel next to the USB ports and stick in a spring-switsh that you can wire up to the headers on the motherboard.
