Very nice mate.
I'm a Holden man myself (drive an LS1)...but I do like the BAs (drove the whole range around Oran Park last year - lots of fun ).
I might have missed it - but where did you actually put the computer? Just there in front of the gearstick...or is that just the USB ports and optical drive?
PS: Nice Powermate. I've got the same black one connected to my computer.
