All black Panasonic Toughbook CF-20
Here goes few pictures of my tuned up Panasonic Toughbook CF-20. After installing Linux on this, I see this to be ready for any professional tasking.
This black back turned out to be pretty nice, hiding brand and model - but making it unique from outside. Highly recommend this modification.
