Haven't seen it mentioned yet, so here goes.
Has anyone checked out the new Carnetix DC power supply? I see it's available in the mp3car.com store for $135

Like the other Carnetix products, it's not an ATX type supply, but provides regulated power for a standard non-regulated ATX supply as well as other outputs for your monitor or USB devices.
What makes it different is the USB interface for monitoring/programming with their PSUmoni application.
On my wish-list.
