Update: I've had several questions/comments about the fact that it's full of duct tape. I'll just say that at the moment it's still very much a work in progress and the tape works well for holding things in place and is also non-conductive.....plus it also holds the universe together so whatever can do that can't be half bad now can it ;). The motherboard is held in place by screws but that's about it.
Things still left to do:
1) cut a hole in the back for the power switch
2) re-route the bluetooth antenna.
3) lower everything by about 5mm (it's a nice height but can be lower still)
4) route an extension cable for sound
5) re-attach the USB port side
6) secure the trackpad and keyboard in place.
7) general tidy up and neaten things off.
I'd like to be able to keep the keyboard and trackpad separable. Once the fun of this little project is over I'd like to have them usable on my iMac (although I prefer the wired keyboard with the numpad)...after all, it's no longer a laptop. It's a desktop and an underpowered one at that (although according to geekbench it will give a dual G5 powermac a run for its money...for whatever that's worth). I doubt it will be used much beyond internet/email....maybe as an AppleTV replacement or something but that's about it I'd think.
Oh...and as to why I chose to pull it apart instead of getting it repaired, potentially for free, by Apple? Simply because it was written off so would have been junked anyway and hacking it is more fun then sending it away. I wasn't confident Apple would repair it for free anyway (under the "dodgy macbook air hinge" excuse)...although technically all the pieces 'could' be put back together if I could remember where all the screws go. If Apple want to replace a bucket of parts for free I'm happy to sent it to them :)
