@ David -- by my eyes, that actually looks to be an incredibly nice, clean, and tidy production. I have a spare motherboard (ignoring busted audio jack and one questionable USB port) for my trusty ASUS 1000HE netbook. I was thinking of desktopping it until I saw just what a mess it would be simply hooking up a power button... the power button PCB connects to the motherboard with a tiny flat flex cable (FFC -- the little white fiddly cables in laptops that like to tear) and the pin pitch is frightening, at best... never mind rigging in a new cooling solution, since the original "heatsink" is the keyboard underlay! And so on.
May I ask how you handled that very issue (power button) yourself? Is video out automatically handled by BIOS or did you have to twiddle something...? Is it still hooked to the old battery? etc.
You can email me off-list if Luke gets ornery ;) but I'm rather curious as to the full implementation and all.
