Here is a side view of the console showing the gray / black color scheme. That is an 8" touchscreen with a slot load DVD RW underneath it. The slot load cd/dvd drive is out of one of my laptops and I just used an external usb case as the housing. Both the screen and the drive are braced pretty well inside the console.
This is the back of the console. I've cut the inside of a desktop computer to fit in the console and mounted my motherboard and the drive tray. The drive tray is out of a laptop so a 2.5" laptop drives slides in and out of it easily.
Here is the same shot with the drive inserted into the tray and the bus cable connected. I don't know if it is visible, but there is a small screw on the bottom right of the drive tray that secures the drive so it doesn't slide out. The drive tray is also mounted on a very very pliable rubber (not visible in the picture) to dampen any shock. I got the rubber from an internal "slide out" style drive enclosure.
