Re: the wood vs. metal file cabinet debate, one of most important things is that the paint is non off-gassing. Most average to high end metal file cabinets have that type of paint or powder coating, and of course if it's wood and not painted, that's not an issue.
Mike, that file cabinet is a beast. With ten drawers that are 40"x52", and fairly thick wood, how much does that weigh, overall? Do you know much about how old it is, the manufacturer, etc.?
