We got a new cabinet and it's a nice place for my little Apple Museum: An original Apple Cube with 450 MHz from year 2000.
It still runs well with Mac OS X 10.4.11, can be remotely managed via screen sharing and used to be my testing computer for PPC applications. But since I dropped my PPC support this year, it may now stay on the cabinet and wait till we need it. There is always a chance you get an old document where the software is no longer available to convert them to a newer format.
The Apple mouse pad there is even older. Over 20 years a give away from one of the Apple Expos here in Germany!
