I've removed the bottom "dressing" section (which holds some of the I/O connectors)? but the next step isn't obvious. None of the manuals I have cover dismantling and the net doesn't have an IPB or similar available. Other people have managed to get inside (I can see their results) so I must be missing something obvious ... Thanks. Antonio
