Here is my setup...Got some new Z-5500's and the Xbox 360 Elite, 360 HD-DVD Drive, Verizon Wireless XV6700, LTB 5.1 Headphone amp w/ 5.1 headphones (not shown), Everglide S-500 Pro Gaming Headphones.
BTW, I hate this desk.
I used to have the exact same desk. I also hated it, fortunately for me I get to deal with crappy dorm room desks, the entire year long since I take summer classes at my University.
The desk is surprisingly sturdy for being made out of particle board though.. I'd reccomend you move the accompanying stand over to the left, and move your second monitor to the left, looking right has to be a killer on the neck for the second display
