I really like the idea of having the laptop built in to the top housing, but I have concerns about vibration and the hard drive. As luck would have it I remember pulling 2 of these 64Gb SSD's from a dead Sony laptop.

All I need now is a msata to 2.5" IDE connector, which I have found on Ebay for £10. 64Gb will be plenty as currently it has a 40Gb IDE drive, of which I am only using 7Gb.
