The acrylic case had the word Prototype but it was lightly scratched off but is still visible. The FCC text is not present and the device HAS NOT been approved for sale or by the FCC.

The metal housing itself is spot welded and has many more screw holes and is raw metal.

The logic board is marked as a prototype unit. Where the serial number on the machine says EVT. There is a 0.75 cone tweeter on the back of the mesh enclosure. It's connected to the motherboard but I have not gotten it to work. There is an active speaker volume adjustment on the OS side that's adjustable so they are recognized.

The VRM had the 4th transistor as some point but it was removed.

The CD rom is MASSIVE, easily 2 inches tall,and has physical eject button.

The chip inside's part number should make it a 400Mhz chip but once I got it to boot, it's a 500Mhz chip. There are weird markings and unusual serial numbers on the chip itself

Also, and this took awhile to figure out, the machine CANNOT run Mac OS X. I'd assume because of the Bootrom it has, and other strange things. I had to boot into the OS 9 side for it to work.

The AirPort card is a prototype and isn't approved

Even the power supply is a prototype
