Cool install m8, I think the pc-in-a-toolbox idea is great - alot less likely to get nicked, easy to move in and out your car etc.
Think I might do something similar in future as Mini's are well easy to break into and my pc is just waiting to get kidnapped
Also like the velcro on back of the screen idea too. Must incorporate that into my new dash...
