Just another update - i fisnished making the case for the computer. Next i have to bondo it to get the dents out and cover up the welds, drill holes for the motherboard standoffs/fans/etc.
When the case is done, it'll be mounted between the 2 rear jump seats in the back part of the cab (where the jack is located). I'm thinking of putting 2 red lights in there too.
