This model represents a scale model of Sun Microsystems E10K computer cabinet.
The default size in 70mm x 39mm x 50mm.

The original computer cabinet was 70" H x 39" W x 50" D.

If you wish to print this model to accommodate a Raspberry Pi, you'll need to scale it up in your slicer to ~165%. That would allow the Pi to fit in the bottom of the cabinet, You would need to cut some holes in the back and side for the various power and USB ports.

Supports are only needed for the door as there is a lip around the edge to fit into the cabinet.
