I have always wanted to do this with 22's on the sides and a 32" in the middle so everything is the same height. Bezel size would be a factor.
Since I took that I removed the stands on the left and right monitors so that the top of the middle lines up perfectly with the top of the left and right (I've found that makes the most sense plus the top of the portraits was too high I was looking up slight and it was killing my neck over a day).
I would like that setup a lot. I keep my start bar at the top of the screen, have since forever, I like it much better up there near all my my program menus. That way in would have one continuous bar going across the top. Because I'm sort of anal about lining thing up.
They started as a joke as I kill every plant I'm left in charge off so now everyone buys me Cacti the sarcastic bastards.
I have that same desk! Sitting at it right now, in fact. I have my two main monitors over on the right side, by the rounded edge. I might try to set it up like you have it, with your monitors in the middle/left side.
