Dual Core Intel Atom Mini-ITX add-in planned for a Hack In Progress:
I've had an ongoing project using a Compaq Portable II as a "keep it in the trunk" peripheral setup for HP_Mini. So far I've gutted it to fit a Card Reader/USB breakout panel, and a 17" 1280 x 1024 HP LCD Monitor into the side of the internal frame for use in portrait mode with the unit sitting on its side. There would be a removable clear cover with a bulge at the top in its current iteration. Maybe I'll find a better LCD candidate with a smaller frame/bezel that won't require the bulge by the time I start fooling around with it again.
I ripped the original 5.25" FDD so all that remains is the mounting frame and flip up cover door. That'll require a slot-loading DVD to be sourced
I've also hacked the original KBD into a custom layout that'd be usable with the CPQP2 or as a stand alone with any other computer. I've got several controllers to choose from, just need to do the switch matrix.
A vacuum-formed CRT Face door will hide a couple of removable drive bays and whatever else I can cram in there behind it. The plexi will be back painted with the ubuntu logo on a black background.
Fitting it with a Dual Core Intel Atom Mini-ITX board I've been scoping out would make it an ubuntu running, stand-alone sewing machine luggable. This configuration will likely still leave room for, the originally planned, Mac Mini to be stuffed in there somewhere as well.
