Well for starters there seems to be problems with wet weather.
The computer and all parts were dry (no leakage) but all the time it was wet the touchscreen wouldnt work - could get the picture up but not operate it.
That 1 is still confusing me as i think it is 100% wet weather related but there is no reason for it.
Secondly when mounting hardrives (normal ones not laptop 1's or anything special) dont try to suspend them to limit the shock as this seems to make em worse. My comp kept crashing - so i took the harddrives and mounted em firm to the boot floor and instantly it stopped playing up.
Oh yeah and mount em on end as any harsh shocks in a car are usually up and down and this way it stops the heads crashing.
End of findings
