A project based off my other instructable dual digital frame/wall mount pc, same idea just smaller.
Step 1: Screen
I cut the same size piece of 1/2" ply for the back piece and had some leftover baseboards from my last project for the sides.
Step 2: Mount the Hardware
I used some computer stand offs to mount the motherboard and two strips of double sided 3m tape to hold the screen in place. A little hot glue for the power brick, dc jack, extra usb ports and power switch.
Step 3: Mounting
A small hole in the back for the power cord and the usb cable for a wireless mouse/keyboard receiver.
A long hinge along the bottom allows for easy access to the hardware just in case anything needs repair.
I found an inexpensive usb powered speaker-bar for the top. Nothing fancy but it sounds great for the small kitchen area.
