I also inherited a Mirror drive G4 tower from a former colleague at Hempfield. I am working on a project for school and this is a perfect machine to turn into a server.
This picture here is what I have however, I have a 17″ Apple display not a 23″. I have 2 17″ lcds in fact, the one is with the G4 Cube.
I also inherited an original 15″ LCD that apple produced. I may use that for the server project. The cube can handle a dual 17″ display setup but I need an adapter. So I am excited to get this project started. I think my room is started to get a little warm with all the computers and monitors that are on and running. Thank god the cube has no fan.

I just procured an old PowerMac G4 Cube this past week. This machine was debuted in 2000 and then was laid to rest in 2001.
