Black Omnia hacker cover, and a silver Omnia standard cover. The hacker cover has cutouts to facilitate attaching various leads… in order to do ‘weird’ stuff. If you’re looking at this, you know what it’s for; if you’re wondering what it’s for… you don’t need it 
Both have never left my desktop and never had anything placed on top of them. No scratches or bends to the metal. Both look perfect. There are no screws to either! You’re supposed to use the screws already fitted to your Omnia.
Update: The silver cover has been put out with the trash… as so much stuff is. Hey, I’ve tried to give away Turris Omnia stuff for free (in the spirit of Open Source) + free postage. Oh well.
