The pie has an operating system on it already, this was used for an audio visualizer and I will leave the software as is for you to play around with. I don't remember the version of the operating system or what else I put on it. Feel free to simply wipe the drive and start over or fool around with the pi OS that's on it.

The PC is already built inside the case with the fan installed and is working well.

I simply do not need it anymore.

I no longer have the box or screwdriver that it came with so all you're getting is the PC inside the case with the power cable. Also included is the mini HDMI to HDMI cable so that you can plug in to a monitor.
