Picked up the PCIe NanoKVM.
Good: Worked right out of the box, cheap, gets powered from PC even when PC is off.
Bad: The internal cabling is pretty messy + poorly documented (specially the USB one).
Ugly: The OLED display is impossible to read, slightly misaligned and mostly pointless.
Might get another one or two if they come up for sale anytime. The Comet is better, but no purely internal version.
