Well I thought I'd just give a virtual tour of my room.
A few things to note first...
I do not have a bedroom, I live in a livingroom (no pun intended).
We will go clock wise around my room.
In the first picture you see the sliding glass door that leads to my patio.
This is where I draw all my cool air from
You also see my videogame rocker chair, cheesey Target shoe rack, my left tower and surround speakers (I'll explain this more later), all my computer hardware/software boxes, Boba Fett & Slave1, and one of my two dressers.
In the second picture you see the main course... All my AV equipment.
Gaining the most attention would be my RCA MM32110 HDTV/Monitor.
It is 32 inches, 800x600 native, and has two VGA inputs among the other obvious inputs. I know your thinking 800x600 is low res, it is. But when you are playing games at this res with AA maxed out on a 32" CRT sitting on a couch, it's way better than playting at 1600x1200 on a 19" one foot away. You see the Toshiba 6 head VCR, woop-di-doo. Onkyo 6.1 receiver. My center channel with Nintendo beanie babes. A heavily modded XBOX. Behind the little door in the middle is a GAMECUBE. You'll see my computer on the right and an external HDD with a Duplo Bunny sitting on it. Notice my computer is sitting on some furniture. Underneath, inside, is my modem and router. Elevating the Sonata keeps all the cat fur from getting sucked into it. Plus better air flow. On my dresser, right side, is an Air-Zooka. If you don't own one, buy one

.
Third picture, right tower and surround speaker. Stone Brewing 3 liters, Kramer, tool box, sub, small dresser. Kitchen in background.
Fourth picture, Phone, couch, surround speakers, framed Nintendo ads from E3 mag (year of GC demo), and more junk.
I don't know why anyone would care, but that's my room.
I feel that there is soooooo much more to a rig than whats just inside, that's me.
About the speakers, I have towers and surround. You need towers for music. Good Ol' 2 channel stereo. Surround music sounds okay at best. Of course I use the surrounds for movies and games...
I think that covers the most of it.
