I too am trying to make a final decision as to where to locate my pc. I should have adequate space behind the centre consol and possibly in the glove box too. Although, I think that a few wisely placed vent holes in the rear and back of the glove box would be in order even though the glove box is not a completely air tight compartment anyway.
It appears that Jan's is in the cavity of one of the body panels. Would that area be safe enough from moisture when the covering panel is placed back on?
