My "workstation" is nothing special. I have of course a pretty large desk. On top of the desk I have two 30" monitors, a keyboard, and a mouse. On another part of the desk, I have my gaming PC. My speakers are mounted up on the wall (two front, two rear, one center) and the sub woofer is on the floor. Behind the desk, I have hidden every wire that my PC uses. I have a UPS sitting alongside the desk on the floor, with it's power cable routed into a wall plate, and from the UPS my devices are powered through the UPS's multiple power ports. From the hardware, the power cables are twist tied together and routed in such a matter to provide plenty of room, but to keep things looking nice and mess free behind the desk. Between the monitors and the PC, I have two DVI cables which are twist tied together and of course routed out of sight to the PC, where each monitor is plugged into it's own video card. The speaker wires are routed through the wall where they join up at a junction, into which it plugs into an amp located next to the UPS, which is connected to the PC via an optical cable. I have a microphone plugged into the back of the PC, and that is routed through the same path the DVI cables are taking (just not in the same cluster) where the mic sits on the desk. My USB devices have their own path, which are my keyboard and mouse which are twist tied together to go to the back of the PC. The CAT5e cable is the only cable pretty much I didn't route specially, only twist tied it together keeping the bend radius of the cable in mind since it had some left over cable on it, as that is going to a wall jack where it is then routed to my basement where all of my networking gear and the Linux router is.
So yeah, that's my setup. I have a rolling chair which also spins on a plastic mat that fits the design of my desk.
I'll get some pics once I get the chance.
EDIT: Forgot to mention that the printers are in the basement as they are running off of the network for network printing.
