That's slick as hell!!! Awesome job dude!
I'm just wondering if you considered using a laptop and buying two docking stations for it - one for use in the house, and the other for use in the car (for example) under the drivers seat or in the trunk.
I mention this only because the newer HP and toshiba models (and i am sure others) come with 160+ gig hard drives in them and they're very fast machines - 2.6 ghz and above. expensive, true, but it's a true mobile desktop replacement solution!
anyway, Awesome job on the casing.... blows away my half-assed efforts by far!
