The Dell U2412M's are LED's, with lower power requirements than typical LCD's. I researched this prior to buying, and it definitely has made a difference with heat. Still, with six of them, the office is noticeably hotter than a room without them.
I also physically relocated my PC to an adjacent room's closet, and just knocked out a small hole in the wall to run the DisplayPort monitor cables, audio cable, and USB cable (connected to a USB hub on my desk). This eliminates heat from the PC, but also makes my office silent.
I have measured the power consumption of the Dell monitors. With brightness reduced to 40% - this is what is most comfortable for my eyes - power consumption is about 14 Watts per monitor.
Running 6 monitors is about 85 Watts, which is the equivalent of a conventional light bulb. The aggregate power consumption of my 3 monitors is 42 Watts, I am very satisfied and do not suffer from excessive heat.
Big Mike/Fat Tails. That is very low heat and power output. I wasn't aware there was such a difference between brands and is something people should consider if going multi-screen.
My monitors are all samsung 245BW. The power assumption according to the default specs is 100 watts for each monitor. I also have them at default setting brightness 100% and contrast 75%. On a very hot day I can cool the room to a very comfortable level in 20-30 minutes.
I also have a commercial grade treadmill in this room which peaks at 20 amps on startup, a massive 1000 watt high current power amplifier and the HVAC. All this lot kept the electrician busy for awhile installing new circuits.
The colors washing out at higher viewing angles is dependant on the LCD technology used. Most standard monitors have not very high viewing angles and colors wash out quickly when viewed from an angle. There is a technology which produces very high viewing angles but at the expense of lower dynamic contrast which makes them less suitable for games and movies (and these two are probably quite important to many, so these high viewing angle displays will hardly ever be mainstream...).
Heat is not such a big problem where I live, people around here traditionally focus on heating, not on air conditioning
Temperatures rarely hit 30 degrees centigrade in summer.
What also helps is that my office is a bit bigger and I have all the other tech stuff ( 2nd PC, printer, NAS...) in an adjacent room. Slightly different approach as @Big Mike but also keeps my office quiet the trading PC is integrated into my desk and is not audible at normal loads. I mainly did that as i didn't want to have to run into an other room and back and forth if I should experience any problems with the computer.
While the concept is cool and executed well, I can't help being distracted by the exposed cabling. I may be alone in this, but I am always trying to reduce the amount of visible wiring/cabling. And it's not even due to pressure to conform to some WAF (wife approval factor).
This is basically a prototype created for Eddi's thesis, so it may be a bit before it or something like it is commercially available. If it gets to that point, hopefully cable concealment gets a little more attention
Edit: Just came across another article about Eddi and his project (have not read this yet): https://goo.gl/g9oMJ

I've been using a couple of these USB to DVI(or VGA) adapters/videocards to hook up more monitors then hook them all up to a USB hub, then to my laptop. Doesn't work well with 3D graphics, but fine for 2D apps and Ninja, ThinkOrSwim etc. I picked mine up at Fry's.
Wow--some professional looking setups. I'd post a picture of my desk but afraid I'd get raided by the Health Department or at least Better Homes & Gardens
Seriously though, while I do well enough have to wonder if I'd do better if my desk were "dressed for the part". The problem is any neatness seems like too much--makes me uneasy. Suppose "only my shrink can say for sure" :-/
A very nice desk in deed, but a bit overwhelming...I would probably do considerably better at flying a space shuttle than at using the full potential of your setup! Makes mine look like a kindergarten toy
Thought I'd share a pic of my desk:
As you can see there is a window behind the screens, so light shining through gaps would probably be extremely irritating. At least it was the main reason to chose this setup...
