I got a 21' inch screen, a basic 10 buck logitech keyboard and a Trust gxt 25 mouse.
Apart from that, I use a Thrustmaster T-16000M Flight Joystick and sometimes a Wireless Xbox 360 controller for Windows.
I used to have the Turtle Beach P11 as a headset, but it broke half a year again and since then I use a Dragon War Garand headset. I liek it a lot, it has so much better audio quality than the P11 for the exact same price. It's also quite comfortable, al though it feels kinda plastic and cheap to the touch.
