Here are some of mine. I just moved into this house in December and my media room is a temporary set up. Next year I am planning a huge renovation down there with new floors, mounting the TV flush, getting rid of the stand, and sinking some big bucks into a full 7.1 surround setup. For now it's a 70" Sharp-Aquos LED LCD 240hz 3D set, a pioneer receiver from 1994 and 2x18" Pioneer 800watt monster floor speakers with an RCA center channel.
360/PS3/WiiU with around 450+ games, 2 complete Move controllers, Kinect, 2 Sharpshooters, 2 Wii Motion+ controllers, 4 360 controllers, 4 PS3 controllers, 4 Rock Band Guitars, drum kit, mic and stand, keyboard, DJ Hero controller, and a Mortal Kombat fighting stick for the 360. Oh yeah, 4 active 3D glasses too. I run 2 TVs down there with 2 360's when gaming with friends. That's the 46" Samsung on the counter.
Family board games are stored in the cabinets along with movie candy, blu rays, game guides, and a Nerf arsenal of about 10 guns with a hundred darts.
Anyway, crappy pic inc:
My computer area is shared with my wife. The large overstuffed chair is between our desks. Her's a goddamn disaster, sorry! Mine is always neat. I run triple monitors with an Alienware something or other from 3 years ago. I upgraded the 5970 to duel 7970's last year and added 28GB of RAM. It can run anything out there maxxed at 5760x1200. Logitech z550 surround, Logitech G35 Headset, Logitech G19 Keyboard, and a Logitech G13 Gamepad. I have a WoW Cataclysm mouse, which I love. All that shit lights up, if you're into that.
This also doubles as my painting area so all of the drawers are organized and filled with paint, brushes, airbrush, magnifier, ect. I have a little fridge there too that holds 4 cans of Mnt Dew. My ipads flank either side of me when I'm down here, playing movies on one and surfing on the other.
Here is a pic from my old house with the setup I'm describing, as well as my movie collection which is still mostly in boxes atm:
I have a lot of toys. I'm glad we moved to a larger home. We needed it.
