Airbus has its high priority equipment located on seperate shelf forward of the nose wheel well (1x Prim computer 1x Sec computer and MMR1). The general stuff is aft of the wheel well and the gcu's are either side of the wheel well. The galleys are no where near any of the electronics - j class is at door 2. They even have 1 adiru located under the floor panel away from the other two. Much better design. High priority power cb's/feeders are remote from rest in seperate cupboard.
