Even then you have other physical issues to consider. This is one of the things I love about the Space Shuttle. It had 5 computers for redundancy during launch and return. You obviously don't want to put them all in the same place so you spread them out among the avionics bays. You also obviously don't want them all installed in the same orientation so you install them differently with respect to the vehicles orientation. You also have a huge data network that requires redundancy and you take all the same steps with the multiplexers as well.
