I have no idea where this came from as my 3000s are complete, but I found a spare metal case part from a 3000 desktop in a parts bin in the basement and I don't want to just throw it away. This is the piece that goes on the right side of the 3000 desktop case and surrounds the keyboard and joystick ports. Asking shipping $1 + shipping + any PP fees to US buyers only. Yup, one measly dollar bill. Hopefully someone up here can use this part. Thanks!
