Look on Hantarex's website for whatever monitor you're interested in. Somewhere on its page will be an Adobe Acrobat file that includes all the specs for the monitor, including physical dimensions. The connectors should be the same, but if they arent, it wont be that hard to swap em over to another style molex.
Something else to consider, Hantarex monitors are relativly expensive. Atleast where I am, you can buy a D9200 for the price of a new Polo.
