Well I still have a few things to do before I readd my dell 2407... Such as buy a new video card. It's gonna be a 7 monitor setup now, with a vertical dell 2007.
I replaced the 15" 1024x768 lcd elo touchscreen with a 17" 1280x1024 (WHICH LOOKS LIKE AN LCD!), and I replaced my w2361v lg with a dell sp2309w (both are 23", but the lg was 1920x1080, and the dell is 2048x1152. I ended up having to replace the lg because it wasn't VESA compatible, which is the main reason why the 6 monitor setup was delayed for awhile.). The lg replaced the dell 2007 from the banking pc so i will now have 7 monitors on this.
here is a shot (Stil 5 monitors):
