Cooling the Server Room?
kolchak asks: "As the Australian summer heats up, we are looking at a cooling solution for our computer room. We have 4 racks (almost all full) with around 40 machines, switches, routers, 2 UPSs and 2 monitors. Unfortunately, its located in the middle of the office with no windows available for ventilation. We can vent the exhaust into the ceiling space which in turn is vented outside. Also, since the room is so small, we need to install any cooling device outside the room (a store room backs on which will house the cooling unit and potentially pipe hot / cold air through the wall). All the units we've seen so far need to be in the room, we just don't have the space. Anyone come across and solved this? Any ideas on good cooling units we can install easily and cheaply?"
one of the best solutions I have seen was at a local isp. They ran copper tubing just above the ceiling (hidden by the foam tiles) in a switchback layout similar to a radiator. They had a small pump just outside that moved water through both the internal and external radiators. It worked quite well and lowered the temperature in their main room by 20 degrees. Wasn't the prettiest thing with the tubing on the outside, but I'm sure you can find a way to hide it.
Ohhhh, look at all the pretty shiny things.

Or search for "cooling" in Ask Slashdot.
I'll boil it down for you:
1: Get professional help (arch, engineer, contractor)
2: Repeat #1.

Here's a wild idea...Go hire some engineers.
Apparently there are whole companies who specialize in heating and cooling.
That will probably work out better than asking a bunch of geeks for a hack without knowing any of the details...
See, I live in Wisconsin. And it's starting to get kind of cold. We'll let you run an air duct from here to Australia and take our cold air, if you put in another air duct blowing some of your warm air back here. Give us a call and we'll talk it over.

...you don't place your servers and build the server room around them. You build the server room first, then you place your servers. ...
so, for future reference, you put the cart before the horse.
...don't do this.
First, it has to be said that when you built your server room you should have planned that before the equipment ever went in. Hindsight.
I'll pat myself on the back here. In my 911 PSAP and dispatch center we have a room that houses the phone system, servers and radios. I have to imagine that this room generates far more heat than what you're dealing with because of the transmitters. There was no environmental control, not even vents. Systems would die or reboot without warning all year round but the problem got worse in the summer.
Nobody knew what to do. Like your situation, this room is in the middle of the building. Every amateur carpenter, electrician, HVAC tech in the police department looked at it and scratched their heads.
Then I came into the picture. Rather than wasting time thinking about the problem or asking Slashdot, I picked up the phone and called the local HVAC shop. In minutes I had not one but two qualified technicians with over 30 years of combined experience at my disposal. Two hours later I had a quote. Three weeks later the temperature and humidity in the room are constant and within tolerance. And we haven't had a single equipment failure since.
The system they installed uses the building water supply to cool air in a machine down the hall. The cool air is vented into the room and exhaust is vented up through the roof. That vent work is amazing, none of us non HVAC techs would have guessed it to be possible.
Do yourself a huge favor and call in a pro.
