I saw a Lite Brite Cube at the grocery store. Cube. Hmmm....
The cube comes with two drawers, and a separating area between them. I cut out the separating area, and cut down one drawer to a false front.
This is a mini-itx motherboard with a 533 MHz EPIA processor. It fits perfectly into the opening. There won't be space for a CD-ROM, but I can use a USB CD-ROM when necessary.
There are small power supplies that literally snap onto the motherboard, with one power unit for a hard disk. The hard disk is mounted on strap of plastic I stretched across the system.
This is the back plane of the motherboard.
