In all Honesty I'd loose the Hutch.
It looks like your primary monitor has its edges cut off by the hutch as well, that would drive me crazy. Whats the point of having a beautiful 16:10 if you can't see the whole screen!
Unless you heavily modify it, I'd get rid of it. I have all the shelf space from my hutch removed for my dual monitors and my tower to have enough room.
not a great pic but the only one I have currently hosted that shows what I mean.
I'd take the cd tray and middle support out of the right part of the hutch and put the secondary monitor in there, as well as try to modify the two middle supports so you can see your whole primary monitor.
Once you get a third display you can modify the left side for the same reason. No need to buy a new expensive desk if you don't mind cutting up the one you have :)
