well, since you don't know the dimensions, i'm going to assume that you haven't purchased it yet....so don't. I bought an xarcade 2 player unit many years ago, long before i ever considered having my own cabinet...and while it did the job, it just can't compare to building your own panel. if you are taking the time to build or convert a cabinet, dont wimp out and throw an xarcade on it. building your own panel is pretty easy, and that way you can make it just the way you want it. speaking from experience, you may be content with the x-arcade unit for a while, but you will soon develope that constant nagging feeling that you could do it better.
