I've managed to insert a motherboard running an intel core 2 duo into this macintosh case and also squeeze in a monochrome CRT monitor
here's a rough set up of the machine running on it's own power. In fact I'm writing this post with it now!
there is a SSF PSU on it's way to replace the bulky atx PSU that I'm using to test the system and a handful of cables and adapters to finish the aesthetics. Figured I'd update you all on how things are going.
